I marked a few coins a few years ago. My ONLY intention was to see if I would ever see them again. I did this when I lived in VA. 3.5 years later, while living back in PA, one of my marked coins showed up. I kept it just because it’s the first ones I’ve found that I marked. I do not mark coins to know if I’d gone through them before. Just did it to see how long it would take and where I would ever see one of these coins again. The dozen coins I marked were in absolutely terrible shape, not coins anyone would consider holding onto.
I always get a laugh when I find a BuffaloBoy coin, I show my wife and explain that it’s another hunter from the “treasure” forum I’m a member of, I just get an eye roll and a “that’s nice”, hahaha.
