I agree with basically everyone, that 80K is insane. But I have a friend that was offered 100k for his and he let it go. So there are people out there willing to spend big bucks for things just to say that they have one.
I remember when i sold a quantum video game about 15 years ago, and was offered 3k for it and thought the guy was insane. After he bought it I asked him a few questions, I asked him why the game was worth so much to him since it was about 6 months worth of payments for the mortgage i had at that time. He told me that he lived in manhattan and that his monthly rent for his 1 bedroom loft was 3k, so it was only one month of mortgage to him. That seemed like a reasonable answer to me at the time. So back on Kingpin, just remember, that there are people that pay that much for a watch occasionally. Just not me sadly
