Hitters vs pitchers autographsThis is not necessarily true. There are many pitchers whose signatures are more valuable than hitters from the same time period. It is possible that overall there are more hitters with valuable signatures than pitchers but this is due to popularity. Supply and demand dictate value. Regardless of popularity (demand) the number of signatures available in the market will be the bottom line on value. Hitters have always been more popular than pitchers and have a higher fan base. This might be the reason why Hitters hold the bulk of the value in autograph prices.
