A market for "known" forgeries? Anything else like this? (slightly O/T)

As far as i know the Roy Campanella stamped signatures still sell pretty well.. I also picked one up somewhat cheap a while back. Heck, I've seen instances of psa authenticating and slabbing 'em, without designating them as stamped(which I despise PSA for). I know for a while he used the stamp himself, as it was easier on him and more legible for the auto seeker. But I also know that a lot of the time his wife did the stamping for him... And I can only imagine that the stamp is still out there somewhere ready to still be used. Any thoughts or opinions on the "Best Wishes Roy Campanella" stamped items?

I'm also aware of some of the silk cachets from the 80's that were originally supposed to have been signed by Pete Rose, that were immediately discovered to be clubhouse signatures, and then returned to Rose to personally sign himself as he was originally contracted to do. Basically, a number of those cachets out there have both an authentic Rose signature and the clubhouse one. I've always found these to be an interesting item, however wouldn't go out of my way to get one.
