Don`t want to rain on your parade but you might find most collectors of boxing memento prefer to buy the pair of gloves rather than one.
One glove looks a bit sad and lonely in a glass case or hanging on the wall on its lonesome.
Alright boys, you know the rules-no holding in the clinches and when I say break I want a good clean break. Protect yourselves at all times. Now back to your corners and when the bell rings, come out fighting.
If it was owned by a GENUINE one legged boxer, yes, it would be worth a mint.
They are extremely rare. Contact Sotheby's Auctions for advice.
Good luck with it.
