You can now organize cards into collections to help you keep better tabs on your own personal collections, or share inventory lists on Discord, Facebook, X or wherever else you sell cards!

Now inside of whuppit, you have the ability to add cards to a "collection". Each card can belong to any number of collections—from 0 to as many as you would like.

Each collection has a public link that you can choose to use if you want to share your collection with anyone—whether to show cards you have for sale, or simply to showcase some of your favorites.

I've been using the feature myself for awhile to try to iron out the wrinkles. Here are a couple of examples of how I've used them.

Ok, look, sometimes you're just really excited about some cards and it feels good to let someone else enjoy them too. I am obsessed with this year's Topps Black & White baseball cards and have graded a fair share. I was chatting with someone and found myself sending a few individual pics, so I put together a collection of what I currently have (meaning, I haven't sold them yet) and shared the link with them instead, letting them look through the collection for themseles.

One thing I've noticed in Discord groups, Facebook, Twitter—really any location people are trying to buy cards—is that people will often post specific players they're looking for and ask what is available.

I've also seen sellers, on Discord in particular, provide spreadsheets showing their current inventory.

Using the new collections functionality, you can create your own inventory collections for sharing. Each card can now have an "Asking Price" that you can set. Whenever a card has an asking price, that price will be displayed within the collection. Each collection also has an optionally shareable public link, so instead of answering with a list or spreadsheet, you can now provide a nice visual way for buyers to quickly see what cards you have available and for how much.

For example, someone was looking for De'Von Achane cards, so I created a quick collection of Achane's I had available and sent them the link. As cards are sold, I just remove them from the collection and keep that inventory accurate and up to date.

I sell almost everything through eBay, but I've started testing the waters on Discord and Facebook a bit more. Because Discord and Facebook postings get buried over time, it's a LOT harder to keep track of what you posted. So I started a little "Discord Inventory" collection for myself.

When I post a card for sale on Discord, I add it to that collection so I can go back and remind myself which cards I've listed there.

Collections are really kind of open-ended, and I'm sure there are a ton of different ways to use them. I know several people have wanted this feature for keeping tabs on their own personal collections

in a more visual way, or tracking set progress.

Collections are in beta, which means there's a lot more I'm expecting to add here over time. I'm already exploring different ways that grading population data might be useful here, how we could make things like tracking a particular set easier, or how we could make it easier for a potential buyer to contact you with interest. As always, user feedback is very appreciated—I pay close attention to what folks are suggesting (this one came directly from a conversation with a user).

So please, keep the feedback coming and reach out at any time—I'm excited to see how people use this!

Every whuppit user now has access to the all-new Profit Evaluator to help you identify the most profitable targets for your raw-to-grade plays.

I've always wanted whuppit to be able to help people throughout the entire raw to grade process. So far, the focus has been primarily on help you stay on top of your inventory and have detailed reporting to help you learn what works well and what doesn't. But there's still actually selling the card and finding the right cards to grade in the first place.

The Profit Evaluator is the first step towards helping you find better raw-to-grade targets.

The evaluator is based on some calculations I've been using the for the past year or so to help me identify good targets for grading. It looks at grading breakdown, alongside card value, to help calculate the Profit Efficiency Factor (PEF), a measurement of how efficient your investment is (higher is better). It also provides you with how much money you would need to invest in that card to get $1,000 profit (just another way for you to gauge efficiency) and the gem rate you would personally need to be profitable.

To use the evaluator, you start by searching for the card you are considering targeting for grading purposes. The tool will search across PSA's entire graded population and retrieve a breakdown of how commonly each grade is given for that card.

From there, you can enter in the approximate value of the card at each grade level. The tool will use those values, alongside the grading data, to calculate the profit/loss at each grade, and the likelihood you are to get each grade. It then uses that to determine how efficient a card is.

Let's go through a couple quick examples to compare.

This year's Prizm release has a very low gem rate, which has (so far) put a little extra premium on the PSA 10's. At the moment (March 10, 2025), searching for the card reveals:

Looking at recent comps (I recommend a tool like Market Movers, 130point or CardLadder), the value of the card is:

Plugging those numbers into the evaluator (personally I use the raw value for 7 or below, only because I expect I can safely weed those out and re-sell raw for a similar price to what I paid), I get a Profit Efficiency Factor of .493. Put another way, we would need to spend about $2,027 between the cards and grading fees to make a $1,000 profit.

That's a pretty low score. While the premium on a 10 is very high, I would need to be really confident and accurate in my pre-grade assessments for this to be a play I would want to aggressively make.

Let's look at another popular quarterback: Drake Maye. Jayden is in a class of his own in terms of market at the moment, so his PSA 10's are significantly more valuable than Maye's, but let's take a look at the actual data for Maye to see how his silver stacks up.

Search for that card in the Profit Evaluator, we see it actually grades slightly better than Jayden's card:

While his cards are worth quite a bit less than Jayden's, the 10 premium is still really high:

Plugging these numbers into the profit evaluator (again, I'll use raw value for anything less than a PSA 7), we get a PEF of 1.597. We would only need to spend $626 to get a $1,000 profit.

Even though Jayden's cards are worth much more, Drake Maye's silvers are (currently) a much more efficient grading target.

The evaluator is live now for all paid whuppit users. My hope is that it helps you identify solid grading targets, so you can improve your profits.

Stay tuned for more improvements to help make sourcing and selling cards much easier soon.

I'm super excited to launch two new ways to add a card to your whuppit inventory, making the entire process much more efficient so you can get on with the fun part of collecting and selling.

There are now three different ways to add cards to your account.

You can now start searching for the card you want to add by typing in any combination of the card's year, player, set, card number, etc. When you do, we'll start to search the massive GemRate database for the most likely matches based on your search term.

When you find your match, you can click on it, and the form below will be automatically populated with the card's year, name, parallel (a new field), card number, player name, sport, and whether or not the card is autographed. You can then fill in any other details you would like.

If you are adding any already graded cards to your inventory, you can use the certificate number to grab the card's information.

If the selected grading company has a card that matches that certificate, the form below will auto-populate with the year, card name, parallel, card number, player name, sport, certificate number, grading company, and card grade. You can then fill in any remaining details.

If you have a bunch of cards to add, the bulk import functionality is your best route as you can upload a CSV with all your cards and add hundreds of cards in seconds.

You can learn more about the bulk import functionality in the announcement post for that feature.

I'm a massive fan of GemRate, and am incredibly excited to be able to start to incorporate their incredible data into whuppit.

These new methods of adding cards are just a start, and already make it easier than every to quickly add cards to your account, while ensuring accurate details.

Stay tuned for more exciting improvements very soon!

There was lots of great feedback around auto-importing PSA images, so the feature is now on for everyone, by default—with no requirement for you to get your own API key.

Here's all you need to do to make sure that images of your PSA graded cards are automatically added in whuppit.

That's it. As long as whuppit can tell that it's a PSA card and the certificate is valid, whuppit will reach out to PSA and grab the images for you.

Lots more great updates coming soon!

[UPDATE] You no longer need your own PSA account or API key—whuppit does this automatically on its own. Read here for more information.

You can now connect your PSA account to enable whuppit to automatically import images of your PSA graded cards.

When you have a PSA account, PSA let's you generate a unique API token for free. You can add that token to your whuppit account in your account settings page. When whuppit sees you have connected your PSA account using your unique token, it will automatically start to import images of PSA graded cards whenever they appear in your custom reports, submissions pages or search results.

You can see this functionality in action in this recent video.

You can grab your free API token from PSA. Once logged into your account, you can hit the "Generate Token" button which will provide you with a unique token.

You can copy that token, and then paste it into the PSA API box in your account settings, and then hit the "Update" button.

With the token added to whuppit, you don't need to do anything more. Whenever a card with a PSA certificate shows up in search results, custom reports or on a submissions page, whuppit will reach out to PSA and grab the front and back images for as many cards as it can.

That means if you currently have more than 100 cards, it may take some time for whuppit to get all the images. When whuppit grabs the images, it saves them permanently so that it will never have to retrieve the same images twice.

I'm hoping to be able to avoid the 100 card per day limit in the future, so hopefully this will be a temporary thing.

Nope. When whuppit gets the images, it saves them permanently so that they are in whuppit forever, without ever having to grab them again from PSA.

At the moment, whuppit fetches images on-demand. That means that if a PSA graded card shows up in your search results, custom reports or if you're viewing a submission in whuppit, it will start retrieving images of any cards that don't already have images stored in whuppit.

There are three reasons why you may be looking at a graded card in your inventory and not seeing any images.

I'm really excited about this addition! Not only does it make viewing your inventory in whuppit much more fun, but it also unlocks some pretty cool functionality that will be coming soon!

The new Monthly Cohort Report lets you track the profitability of your monthly purchases over time.

The new report shows you:

This report makes it a lot easier to:

You can click through on each individual month to get a detailed report of exactly what was purchased, with advanced filtering to be able to get more granular detail on what has sold well and what has been sitting around in your inventory.

The hope is that this report will arm you with the information you need to better anticipate future profits as you refine your strategies.

It's now easier and ever to get started with whuppit by importing directly from your existing spreadsheets or other tracking services, with the new bulk import functionality.

A lot of folks maybe using their own spreadsheets for tracking their profits and grades (I know that was what I did at first!) and don't want to lose that data. Manually adding each and every card is time consuming and tideous.

Now you can directly bulk import 1,000's of cards in seconds using the CSV import functionality.

You can save your existing spreadsheet data (Excel, Google Sheets, etc) as a CSV and then import directly into whuppit. When you do, you will be able to map your existing columns to whuppit fields.

When you select a field to map, an example from your spreadsheet will be displayed to help you make sure you're grabbing the correct columns.

There are also a few intelligent defaults in place to help you out.

If you don't currently distinguish between raw and graded cards in your spreadsheet, whuppit will automatically flag any imported cards with a grade or certificate number as graded.

Similarly, if you don't currently track a status, whuppit will mark all cards as "In-Hand", unless there is a sales price for a card, in which case the card will be imported with a status of "Sold".

The import functionality is in beta, and already has been improved quite a bit by early feedback from some users. I'm excited about making it possible to populate whuppit with tons of data in a matter of seconds!

The search functionality has been expanded to allow some advanced filtering, similar to eBay's search functionality.

Wherever you search in Whuppit, you can use the hyphen as a negative filter, filtering out any cards that match that criteria.

For example, the following query would pull up any cards that contain the words "prizm" and "ginobili", but filter out any cards that also contain the word "select"

You can also provide a group of words within parentheses and separated by comma's to apply OR logic to your search.

For example, the following query would return all cards matching "topps now" and all cards matching "bowman now":

Finally, you can combine negative filters with groups to exclude groups of words.

The following query would first find any cards that match "topps now" or "bowman now", but then filter out any cards that also contain "hannah" or "cooper":

The new search improvements should make it easier than ever to find the cards you're looking for, as well as build granular custom reporting.

On the seller report page, you'll now find a bookmarklet that will let you quickly check any seller on eBay to see if you've bought cards from them and, if so, how many were gradeable.

To use the bookmarklet, drag it to your bookmarks bar. A new bookmark should appear titled "Check Seller on Whuppit"

That's all it takes to install!

To use it, simply navigate to any listing on eBay and click the bookmarklet. It will automatically grab the seller ID and then forward you to your whuppit seller report for that seller.

With the bookmarklet, it should be easier than ever to zero in on the seller's who tend to sell highly gradable cards, improving your gradability rates and profit in turn.

You can now set the grading company for a given order, with options to select from BGS, SGC, CGC and PSA.

You can set the grading company for an order, or for individual cards.

If a card is already attached to an existing order, it will automatically have the appropriate grading company attached.

If you're grading cards with different companies (or simply selling already graded cards), you'll be able to apply the grading company as a filter in your searches and in your custom reporting, enabling you to see important differences between profit and grading accuracy across different companies.
