I have a few dozen fairly nice graded t206s but I am hardly a prime collector and don't check prices regularly. However, I noted what seemed to be unusually strong prices last night for such in the PWCC auction, at least for the PSA 5s and especially the 6s. There were a few startlingly high bids--even $1000 or more--for a few common 6s that were only somewhat scarcer than the norm, or were "highest" for not-so- scare backs such as EPDG. Maybe this means nothing because PWCC usually generates higher bids, but what do you think? Pehaps there's a new group of registry people aiming for 5s and 6s?
