A few pictures of some of my finds over the past couple of days. The large one cent coins are 1797 I believe - they are fairly corroded and worn down. If you have some tips on safest way to clean I'd love to learn from your experience.
Absolutely! Early stuff for sure. I for one save the early glass pieces (particularly the harder to find colors of cobalt and teal) and polish them in my rock tumblers until they look like molten pieces of sea glass.
All your pottery shards look so beautiful laid out like that. That would look great in a display case.
I'd hate to be the one to give you "unsafe" advise there are several ways of cleaning coppers, best advise is practice on newer copper coins that might not be of value to you. There is a "cleaning and preservation" forum to help give you ideas. There are a wide opinion on the safe way of cleaning. You might have to come up with your own way.
