i love that this has accidentally turned into a "what's my super rare dennis schroeder worth?" thread haha.
SteveO, in regards to that test refractor... a lot. The rack pack, cornerstone, and lottery prize test refractors go for a ton because nobody is certain of the scarcity, though my understanding is that most believe 5ish copies, give or take, of each card made it to market. I would think $150-$200 is a reasonable estimate, but if two supercollectors were battling over it that could double easily. I'm basing this mainly on what I paid for my Mitch lottery prize test refractor ($250- double the 2nd most expensive Mitch in my collection to date). I'm guessing Mitch has a bit stronger following but your Damon has much better centering- lucky you haha
