:rofl @ the reaper comment! After Manny retires it could be worth alot though.....and after he dies if he is looked upon in the same way as he is now it could be tremendous. The key is to keep it for as long as you can (all the other hundred people would have lost theirs or thrown them away) and in as good condition as you can.
But honestly! I have a ton of autographs, rookie cards, things i have been sitting on for years! They lost Value! I would never sell them unless I am about to lose my house! Id keep it! and you other gloves signed! Unless ur hard up for money!
or even test the E bay Market! Put it on there for a week! and take it off before sell date is over! Just to see how much you could get!
You can go on the Boxing Hall of Fame and in their online store guys like Sergio Martinez,Erik Morales go for $85.. I would estimate those 2 for a signed glove for around $200-$300.. I would not see it going over $300 imo
Last time I checked a signed glove by Pac (one glove) was going for $150+ on ebay. I think the value has peaked. You have to consider the value of the gloves too. A pair of Cleto Reyes gloves go for around $130 brand new.
