What's not to believe? It really is a genuine $100 poker chip. Although I don't know, did Sahara Reno have poker? And it's probably a little inacurate to describe chips from a place built in 1979 as "1940-50's" vintage, but what's a few decades plus or minus? Are you saying you think the reserve might be a little high?
