Definitely has a ton of value to it - I've not seen one for sale recently so pricing is difficult - I'd say at least $1000 but I wouldn't be surprised if it was closer to $2000 - they are definitely rare. If you were looking to sell I'm sure you'd have many interested buyers.
If you have an interest in trading let me know if I have a glove you might have an interest in. Very cool mitt. just drop me an email at cunninghamd1707 @yahoo.com Not sure what kind of gloves you like.
