Glad you are still out digging. It’s good and fun to find coins but really getting the trash picked is good for everyone. We do our fair share being one of the clean up crews.
I did a very small fresh water beach a few years back that is a popular summer spot. What I found was hundreds of nails scattered all over in the sand on that beach. Looked as if someone distributed a whole big box of nail out of spite for some reason. I now have a lot of new nails in the shop. They were large nails and I was thankful for that. I was there the better part of a day trying to get them all.
