It will go for more than what the second highest bidder bids
And the serious answer is - who the hell knows! Are there many player collectors out there ? Whats other Nash 1/1's gone for in the past ? It's impossible to guess accurately - anyone remember the Alonzo Mourning Finest 1/1 which went for over $1000 a while back (and I believe is still one of the highest prices for a Finest 1/1 yet) ? It went for that price because of what I said above .. so it is IMPOSSIBLE to guess.
