Grading math

A PSA 10 sells for 10.0x the raw price. A PSA 9 sells for $1,487.50, 1.8x raw.

Even a PSA 9 ($1,487.50) sells for more than a raw copy plus $79.99 to grade it (PSA Priority, for cards valued up to $1,500) ($903.03 total), so grading pays if your copy is clean enough for a 9; a PSA 10 is upside on top. Most raw copies grade lower than a 9, so check condition first. This is a rough guide, not a guarantee.
