Grading math
A PSA 10 sells for 24.7x the raw price. A PSA 9 sells for $6,000.00, 21.8x raw.
Even a PSA 9 ($6,000.00) sells for more than a raw copy plus $599 to grade it (PSA Premier, for cards valued up to $10,000) ($874.45 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.
