I just recently found my old marble collection that I had as a kid. I'm more than sure it's all common marbles. They were all bought from retail stores. They're all dinged up and some have lost their clarity from my friends and I playing with them back in the late 80's. I'm here because I'm thinking about casually collecting marbles again. Nothing rare though. Just collect common marbles that look cool. Or even lots that are relatively cheap. So here's a question. What's the average price for a lot of common marbles? Or more specifically, what's the price of a single common marble? I plan on spending some time lurking around here checking out old threads to learn more about the hobby.
