I had two signed letters on official documents and got in the $2000 each range for them. One sold last year in REA. There are more than twenty out there, he was a willing signer through the mail for years but the interest level was low at the time of his death. In the mid 1980's you could buy him from autograph dealers for about $5 each and several dealers had 3x5 cards and cuts on hand (reputable). Still though, even if there are a couple hundred out there, that is still a VERY low number for a Hall of Famer and the demand is high. Many are tucked away in pretty advanced collections. I know of at least two single signed balls that are authentic and have wonderful provenance of personal meetings with Foster in the mid-1970's. I would bet there are less than five known but probably a few more in collections that nobody knows about.
