A market doesn't have to make sense for it to exist and for people to run prices up, speculate, etc. It just needs enough "players" buying into it, feeling that even though what they're paying is HIGH, it's still not at the top. Just look at what happened with Bitcoin for a while. As long as it looks like the market will keep trending upward, all is good. Soon as it's no longer all rainbows and sunshine, people are a bit more careful in throwing money around. I'm with others here in regard to the next economic downturn deciding where the peaks of pricing occur.

I've been wondering if there are any other recent collectible / hobby markets that have seen this kind of rise in pricing in the last 3-5 years. Aside from video arcade games that is.
