1. Car collecting. Don't even want to discuss.. haha
2. Bourbon collecting. Can be fun to track stuff down and the clubs associated are also a good time. Starting to have the same effect as pinball, rarer bottles have skyrocketed.
3. Vintage coin op equipment. I collect the history of my business so most games we already have, I am usually looking for very old things. Pre war stuff
4. Currency. Rare bills or unique bills and coins. More people are in this than usually. Seems like a huge influx during covid.
