How to read this board
01 · What it showsPSA 10 price divided by raw price for each card, and how that ratio has moved over about six months.
02 · Premium is not profitMost raw cards do not come back 10s, and the multiple ignores the grading fee. Grading Signals weighs the gem rate and fees.
03 · A compressing gap cuts both waysThe premium can shrink because raw rose or because PSA 10s fell. Check which side moved.
