Here are a couple of links that show the whole panel(of different players). Interesting pieces for sure. I'd guess the best way to sell these would be auction format. Then they sell for whatever someone is willing pay. I'd say challenging to price, not an expert on these though. Obviously, Billy Hoeft is no Hank Aaron.
