Retro collecting is already out of control, prices are becoming more and more ridiculous with the number of collectors and resellers growing.
I'm seeing a lot of young people getting into the hobby, and I've noticed a trend where new collectors are willing to pay much higher prices and they seem to want to amass instant collections, buying items in bulk.
We have a franchise of game stores here named Gametraders, they predominantly sell new gear but also specialise in trading and selling of used gear, including retro items. A few years ago, before retro collecting became cool, they were selling boxed consoles (things like Mega Drive's and SNES) for $30, and games for $5. Nowadays the same consoles sell for $200 and any loose cart with Mario or Zelda on it sells for $50+. I think these prices are crazy but the stuff still sells.
I'm hoping that there will be a turnaround and prices will return to a more respectable level, but we're a long way from that happening. Kind of like how baseball cards, which at their peak some of which were worth thousands but are now more or less worthless due to a complete lack of demand.
