Help, found Wilson "The Pro 88"

[rrivets]

Just got a Wilson "The Pro 88" and was wondering if anybody knows anything about thei glove. It was made in the USA and is 13" in size. It has an H web and everything is original. Broken in but no ink and no chafing or rips. It has the round circle with W in it and the words "The Pro 88". The circle label has USA and it is stamped made in USA on the back. Can anyone tell me when it was made and what it would be worth. It is used like I said but not abused and can be used for hardball or softball. Please help me figure this one out as I haven't seen another one. Thanks
