I recently wanted to find that out, so I took a large part of my coin finds to my coin store that I’ve sold gold and coins to before. I assessed the value in my mind to be 600$, I wasn’t interested in a penny less. 700$ would’ve been better, 800$ would’ve made me smile. He wound up giving me 1,100$. Needless to say I undervalued what I had, so be careful about setting your bar too low, coin shops get GOOD money for things you think aren’t that great.
Did I “make money” in the long run? Hardly, the price of going metal detecting to find all those things is many times that I’m sure. Hobbies rarely pay for themselves in the long run, but money isn’t the objective for most of us here, it’s the challenge and thrill of the hunt that you can’t put a value on. Those who understand do, those who don’t cannot.
