How a show works

Three steps, every show

Listed before we go live. Every card is photographed front and back and listed before the show starts, in order, so you can pre-bid on the ones you want and never miss one in the rush.
$5 starts, short auctions. Singles open at $5 on a ten second clock that extends while bids keep coming. Slabs and higher-end cards carry a Buy It Now so you can take them without waiting. On auctions the room sets the price, not us.
Packed right, scanned next business day. Sleeve, top loader, team bag, bubble mailer. Your wins from one show ship together, scanned at the counter the next business day, with tracking.

Did you know Any giveaway we run is free to enter. No purchase necessary, ever, with the official rules posted in the show.

What we sell

Four sports and one game: rookies, parallels, slabs, legends

The lineup
Modern rookies and parallels	Topps and Bowman baseball, Topps Chrome basketball and football, numbered parallels, refractors and autographs of the players people are chasing this season.
Graded cards	PSA, CGC and SGC slabs, listed with the grader, the grade and the cert number so you can look every one up yourself before you bid.
Vintage and legends	Hall of Famers from the 1950s through the 1990s, honest about condition, with the flaws in the photos and in the description.
Pokémon	Singles and slabs from the first Base Set through the current sets, holos and full arts, graded and raw, plus sealed packs and boxes when we have them.

Real photos. The card you see is the card you get. No stock images.
Priced off real sales. Starts and Buy It Nows come from recent sold prices, not asking prices.
Straight dealing. No raffles, wheels or chance games, ever. Any giveaway we run is free to enter, no purchase necessary, with the official rules posted in the show.
