Yep - overlay KISS did go for BIG $$$!! The buyer was also looking to purchase ANOTHER as well as many other coin op stuff. But.... money is no object to a buyer like this and the value of anything is irrelevant as the pockets are deeper than the ocean.
Buyer is only interested in minty games.. if they want it, then they can make an offer that would be impossible to refuse and are prepared to do so as has been seen with the overlay KISS.
So yes, its possible that another could be sold at such a price.. wont be this one though, and i may be wrong here, but i did hear that the 2nd KISS was found and bought.
Question now is... do they want 3?
