I think I paid under $2,000, back in the very late 90's. It seemed like a ton of money to me.
Even then it was popular and hard to find. The one I got had come off route and I bought it through the local operator. It was in very good shape, and still have it today. It will likely be in here until the bitter end.
I remember buying NIB Revenge from Mars shortly after. I played it for about a year but decided it was too much money tied into a so so game and it is long gone. I don't regret selling that one.
