| description | Use when evaluating, sniping, or selling a 1/1 card. 1/1s have unique pricing dynamics — no comp data, auction discovery only. |
1/1 cards lack pure comp data. Price by triangulation: parallel ratio, player tier, era, and recent 1/1 sales for adjacent players.
Estimate 1/1 value:
1/1s belong at Goldin, PWCC Premier, Heritage Premier, or Fanatics Premier. eBay BIN on a 1/1 loses 30-60% vs auction discovery because the wrong buyer audience sees it. Always auction.
Grade every 1/1 before sale. Raw 1/1 sells at 0.3-0.6× of a PSA 9 graded equivalent. The slab adds liquidity premium and authentication finality.
Sniper tool flags 1/1 listings with raw-card discount potential.
