Single silver coin

[Crispin]

Pulled this one out of same site yesterday. It was very, very deep. I thought it may have been silver and it has been soaking in vinegar for over 24 hours. I put it back in vinegar. I had a couple other pieces that I was pretty sure were pennies and put them in vinegar too. Those pieces are almost completely dissolved. I used nitric acid to test it. I know people may think it is a penny; however, copper turns bright blue in nitric acid and zinc has a violent reaction and gives off black smoke. Silver turns white. I almost didn't want to test it. Probably should have taken pics before I tested it...thought for the next one. Don, see if you can make anything out of this one. This is me taking pictures through my loop. I can ask wife to take better pictures tonight if needed.

The bottom pic seems to have two columns. Maybe there are three and, if so, it might be a nickel three-cent piece from between 1865 and 1889. The diameter of a 3-cent piece is 17.9 mm (same as the 'rosie').

Yeah. I see what you are talking about. Probably would have a third column if I hadn't burned it off testing with acid...smack. I will let it soak in vinegar and see what happens over the text few days. Anything more aggressive will destroy features.

Doubt this is of any help but this is what it looked like coming out of the water:
