Cleaning Pennies
Posted: Mon Feb 06, 2017 4:08 pm
So I cleaned a small batch of copper pennies with a vinegar and salt solution. I let them dry on a towel after they were completely rinsed off with tap water. I was wondering
if they might change color or grow some kind of verdigris. I like my coins to be clean. I will not clean any numismatic ones.....
Has anyone else among our fine community done this before? Thoughts.
