What Is Probstein123?

Probstein123 is the eBay username and store front for Rick Probstein's sports card consignment business, also branded Probstein Auctions or P123 Auctions. Collectors mail in cards they want sold, Probstein's team lists and manages the eBay auctions or Buy It Now listings, and the consignor gets a cut of the final sale price once it moves — the same basic model as sports card consignment generally, just running through eBay's own marketplace rather than a standalone auction site. Probstein has been one of eBay's highest-volume sports card sellers for roughly two decades, with a storefront that regularly runs thousands of active listings at once.

• Mail-in submission— consignors ship cards in (graded slabs and higher-value raw cards); Probstein's team photographs, lists, and manages the eBay sale, then ships to the buyer once it sells.
• Tiered payout rates— reported rates have put graded/higher-value items in roughly the 85–95% payout range (an effective 5–15% commission) depending on sale price and category, with lower payout percentages for cheaper items and bulk lots. Rates have shifted over the years, so current terms should always be confirmed directly before shipping anything in.
• Minimums apply— low-value raw cards (roughly under $35) are typically not accepted and get returned to the consignor rather than listed, since the listing effort isn't worth it below that threshold.
• No storefront browsing required— because listings run on eBay itself, buyers shop and bid the same way they would on any other eBay sports card auction, with Probstein123's feedback history and seller reputation as the main trust signal.

In late 2025, Rick Probstein tried to move his consignment business off eBay entirely, launching a standalone auction platform called Snype. The launch went badly: technical failures caused auctions to end prematurely during the first live sales, and collectors reported that bidder and consignor personal information — names, emails, addresses, eBay user IDs — was exposed to anyone with basic technical know-how. Snype went offline within about a week of launch, and on November 24, 2025, Probstein confirmed a full return to eBay, cancelling every Snype transaction and refunding all funds. It's a useful reminder for consignors generally: a seller's reputation and payout rate matter, but so does the platform's operational track record when something goes wrong mid-sale.

• vs. PWCC Marketplace — PWCC runs its own standalone marketplace and weekly auctions with a Vault storage/lending layer built in. Probstein123 sells through eBay's existing marketplace and buyer base rather than a separate site, which is exactly what made the Snype attempt to compete with that model such a stress test.
• vs. COMC — COMC warehouses your cards and lists them long-term at prices you set (or accepts standing offers), with no consignor action needed per sale. Probstein123 runs items through eBay's auction/fixed-price format with its team actively managing each listing rather than a self-serve storefront.
• vs. Fanatics Collect and catalog auction houses — catalog houses run scheduled, curated sales with buyer's premiums layered on top of the hammer price. Probstein123's listings run on eBay's normal auction/Buy It Now mechanics, without a separate buyer's premium added at checkout.
