Just wondering if anyone knows why my silver coin started to go dark when cleaned with electrolysis. It's a 1920 sixpence that is fairly worn and was fairly clean which is why I experimented with it.
I used a 8.4v / 1amp power supply with a salt water solution.
My copper coins don't go darker just wondering why silver does.
