As someone that buys and sells (to support my own card habit) almost daily, I'm constantly running across buyers and sellers who use past sales as definitive current value. I use to subscribe to VCP but I found the market move too quick these days. To shorten my point, PAST sales are just that, sales in the PAST. That particular deal is done, over, complete. There are thousands of completed sales that I'd love to have bought or sold a card at the price. Sure, using prior sales as a EXTREMELY loose guide can be helpful but what matters is how much can you buy a comparable card for TODAY. Another aspect that gets lost in "comps " is no two PSA 1s or SGC 3s etc are the same. Every 50, 70, 110 year old card aged differently.
I learn something from this site daily, curious how other far more seasoned, intelligent minds in the hobby than I feel about this.
