Selling my 2019 topps on demand Mace Windu card if anyone is interested.

Whatnot is a popular auction app.

Think before you bid / buy.

Does anybody here know what this card might be worth I’d like to list it but I would like to get an idea of the value.

I'm a solo developer and I've been building this because every scanning app I tried would tell me a card was worth some number that no human being has ever actually paid.
So I built Broad Street: Card Scanner. You scan a card - raw or slabbed, one at a time or a whole page of 9 - and it shows you what that card has actually been selling for.
Then you tap PSA 10, PSA 9, PSA 8 and see the graded prices next to the raw price, so "is this worth submitting?" takes about five seconds standing at your kitchen table.
The thing I care most about: the prices are from real sold sales, and the app refuses to fake it. If a card doesn't have enough sales history to honestly compute a 7-day change, it shows nothing instead of making up a percentage. l'a rather show you a blank than lie to you.
(Also, tap the card on its detail page - it flips over, and the back is a stat block of your copy. Collectors seem to like that one. And when you've scanned a stack, one tap exports the whole thing as a priced PDF binder sheet - total value at the top. There's a Market tab for the day's movers too.)
It's free. No subscription, no paywall. iOS only for now.
What I'm asking: scan your weirdest stuff. Junk wax Donruss, 90s inserts, obscure Bowman parallels, off-brand slabs, whatever. When it gets something wrong - and it will - comment or DM me the card. I report data errors upstream and they get fixed fast (last one was fixed same-day). You'd be making the tool better for everyone.
Link in comments. Be brutal, I can take it.

hi just wondering what my card is worth. I don’t really collect much and this was my first pull. Can any collectors determine the value?

I went back through the famous story about Sy Berger and the unwanted 1952 Topps high numbers, expecting it to be either clearly documented or basically hobby folklore.

It's neither.

Berger gave a pretty detailed first-person account: roughly 300-500 cases, three garbage trucks, a friend's garbage scow, and a disposal several miles off New Jersey.

But some of the details get strange.

An older PSA article stated that the cards were dumped into the Atlantic in 1960. A newer PSA history uses much more cautious language and calls it “hobby lore,” saying the cards were allegedly dumped.

The famous two-million-card number can apparently be traced back to Berger himself, but I couldn't find surviving Topps inventory records independently establishing that exact quantity.

There's also a funny numerical detail: #311-407 is 97 cards, while one early Berger account reportedly referred to 96 late cards.

And Willie Mays #261 sometimes gets folded into retellings even though he isn't part of the final #311-407 high-number run.

The Rosen Find creates another rabbit hole because major sources don't even agree cleanly on the year/location.

I put the sources and contradictions together here if anyone wants the full rabbit hole: Did Topps Really Dump Millions of 1952 Baseball Cards Into the Ocean?

I'd be especially interested if anyone here knows of contemporary Topps paperwork, newspaper coverage or other primary evidence that isn't usually cited in versions of this story.

He was bummed he couldn’t find Topps chrome, so decided to rip some unlicensed Donruss. He didn’t realize his auto was a nuke! 🤣

I've been building BinderTrax, a trading card app that combines everything collectors and card dealers usually juggle across separate apps and spreadsheets into one place. Looking for a handful of testers on Android before a wider release.

I'm a developer by trade, and I've been using Card Dealer Pro and Collx for a few years. A few months ago I finally got frustrated enough to build my own app and put it out there with the million+ other apps. I was tired of CDP not making an effort to match TCG cards, making a weak attempt at sports cards, and having a 9% accuracy success rate. I tried making suggestions to their leadership, tried to explain how collectors and resellers actually do things, and they brushed me off, not to mention the constant errors you experience on both platforms.

What it does:

Scan cards instantly with your camera — identifies the card, pulls live market pricing, and adds it to your collection in seconds. Supports Pokémon, Magic, Yu-Gi-Oh, One Piece, sports cards, Funko, and a dozen+ other TCGs. Batch-scan a whole stack at once, or fly through cards one after another with the live scanner. The only thing we don't currently support is graded card lookups, but that's, hopefully, coming soon.

A real digital Binder for your collection, with live market value tracked automatically as prices move. For TCG, we have a ghost binder when viewing by set so you can see what you have and what you need.

Plus, my favorite, the PokeTrax (Pokedex) is where your cards build your Pokedex. Scanning a higher rarity will replace a lower rarity in PokeTrax.

Duplicate copies of the same card are grouped together in the Binder instead of cluttering your view, but each physical copy still tracks its own storage location independently — so you can have five copies of one card split across different boxes/binders and the app keeps that straight.

Full inventory management built in, not just a collection tracker — locations, stock levels, receiving, for anyone running this as a side hustle or business.

Barcode scanning for fast lookups, plus the ability to generate and print real barcode and QR inventory labels — no separate labeling software needed. Plus, you can scan your own QR or barcode when selling at shows to remove the card from your eBay inventory so you don't have to remember to do it after you get home.

Sell straight to eBay, including eBay variation listings (one listing, multiple card options a buyer picks from) that keep each copy's storage location attached, so when a variation sells, the app tells you exactly which physical copy to pull and where it is.

A point-of-sale checkout for in-person sales, with barcode scanning and QR "scan to pay."

Market trend tracking and a Dealer Hub showing what's moving, what's hot, and your own collection's value over time.

A condition "Appraiser" tool — photograph a card's front and back for an advisory centering/condition read before deciding whether to grade it.

A deck builder, wish list/buy list, and eBay price comps lookups.

What testing involves: install the app, use it for real over the next couple weeks (scan some cards, browse the Binder, try an eBay listing if you have an account, print a label if you have a printer handy), and tell me what breaks or feels confusing. This is Google Play closed testing, so it's low-commitment.

Yes, this app will eventually be paywalled because infrastructure and data API's aren't free, but I feel like the price per tier is competitive with other offerings because you get more with BinderTrax.
