In mint they would be getting up to that value. I have only ever seen Langlands on ebay 2 or 3 times and in poor to fair condition I have one in mint and another with a fine paper crease which is hard to see cnrs are pretty sharp
My other holy grail set would be my mint set of 64 scanlens any one interested in a mint set
For me it would be my 1995 Unredeemed { Unpunched} Kmart redemption card of Mal Maninga The only one that I know that is unredeemed please let me know if anyone else has one I know of only 4 that exist
