Gotta say, making collectibles sounds like a cool side project to do, and I'm confident there's a market for them.

Of course, Etsy is probably the main platform to sell these, and it's full of copycats so anything that looks like it could make money will quickly have cheaper made duplicates flood the market. And not just Etsy, inventions like the fidget clicker box and -spinner saw the might of Chinese manufacturing and drop shipping spin up almost overnight and flood the market with them.
