No offense intended to you BryBo...but if I was a potential buyer, my question of concern would be...
Why do you have it, is it yours, was it given to you, or are you trying to sell it for someone else? Do you have documentation of ownership, so as to verify it's legit? If so, why try to sell it in fan forums...why not contact a professional broker to auction such a rare, very valuable, & historic piece of jewelry?
I assume the wives bracelet is a mate of sorts to the Championship ring given to their player spouses? As such, it's likely pure gold with diamonds, etc..
Such a piece of jewelry as you've described, has the potential to bring thousands if promoted & auctioned professionally, much more than one would be likely to negotiate on a fan forum. Just sayin~ :/
There is the info you need Bryan, thanks to CJ! Now if you have such, then contact a jeweler and find the value.
