Hard to say since they only show up on ebay every several months. I think this might be only the second or third one that I’ve seen.
It really depends on who’s bidding at the time and how badly they want it. I got mine for a true steal at about 250. I had bid more than double that.
Museum of yoyo history has it at $650. Because they’re so far and few between there’s really no expected price, might get lucky might not, it will depend on the bidders, the condition and the timing.
