Based on what I've read here and by a misreported price on a card that I purchased on eBay, I don't have a lot of confidence in PSA's numbers.
I recently made an offer of $600.00 on a 1960 Eddie Mathews PSA 9 offered for sale on eBay at $649.95. My offer was accepted and the transaction went smoothly. (Yes. I know I overpaid.) However, PSA is reporting the purchase price as the original $649.95.

Does anyone know if Vintage Card Prices numbers are more accurate?
