Pinball machines hold their value or go up quite a bit. Kind of large but at least you can play with it as it grows in value.
WWII Enigma machines have gone way up and continue to go up. I would buy one if I could afford it as I expect they will continue to climb in price but they are many tens of thousands of dollars now.
