What I know is that the rules have been changed recently, and all matches will be 3 sets exept for men's Grand Slams (5 sets). So now the masters series final should be only 3 sets.
I do believe so. Most of the time proof coins go up in value more than regular uncirculated ones. Proof state quarters from 1999 have gone up in value.So yes I do believe the set's value will go up in in the future.I hope this helps answer your quest...
While it would look sharp after you're done, how many are left in restorable condition? When it comes down to it, how much are you willing to spend?
