Vintage Bakelite is in great demand by collectors thus driving up the prices. But there are still a few smaller vintage stores here and there that don't know what it's worth. I picked up my pink Bakelite bangle at Value Village for $1.99!
BTW if you want to know if a piece of Bakelite is real or fake, you run the piece under hot water for a few minutes and if you get a faint formaldehyde smell, you've got the real thing.
