1-of-1 Card Economics

1/1 cards lack pure comp data. Price by triangulation: parallel ratio, player tier, era, and recent 1/1 sales for adjacent players.

Triangulation pricing

Estimate 1/1 value:

1. Find PSA 10 base card recent comp
2. Multiply by parallel /5 multiplier (typically 50-150×)
3. Multiply by 1.5-3× for 1/1 scarcity premium
4. Adjust for player tier (HOF +50%, current MVP +30%, journeyman -30%)
5. Sanity-check against last 5 1/1 sales for same player or adjacent tier

Auction venue selection

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.

Grading necessity

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.
