Primarily my question is, why are some selling for so much? They don't seem to have autos or memorabilia pieces. They are just artistic. Are they hard to get? Are they expensive to buy from Topps?
For example, from what I can understand, this George Brett card sells for thousands:

There's over 1000 of them. What was the initial sale price?
Wow crazy. I just can't believe there are thousands of people who want player X's artistic card to the point that they are pushing these cards into the thousand dollar plus territory
