? about Auction Prices Realised on website
Within the Auction Prices link, there's a "Prices by Grade", then "Average Price".
So, does anyone know how PSA comes up with the average price? Do they use the last two sales and divide by 2? Do they use all the sales within the year and divide by number of sales? Do they include qual grades?
I can't seem to do the math that comes up with the number I'm seeing on certain cards. Maybe I need to email PSA and see what they say...just thought someone here might know how they arrive at av price.
