If they happened to come from the website I'm thinking of, and I'm guessing they are, then you are likely paying fair market value. All SGC graded, all Piedmonts. An original find of 800+ cards.
Purchased a Young, McGraw, and Bresnahan from him the other day. Looks like someone purchased the 300+ T206's all in one shot. The seller is a really nice guy.
Edited to add: If this isn't the website, then kindly disregard
