I thought I would try to clean up a few of my finds using electrolysis ... Here is my rig ...
My power supply is a fancy one that allows you to control voltage and amperes ... It really doesn't matter about voltage it's the amps that is important so I set mine around 1.8 amps
You suspend the coins in a saltwater bath - the more salt the better ... And then a piece of metal on the other side to draw the crud to it - reverse plating
I use copper wire to suspend the coins and the rule about amps is checking it bubbles like soda pop not a boiling pot of water ... A couple of hours later and a scrub of bicarbonate and they look like this ...
As you can see most are toasty - what are the chances of finding (2) 1917 shillings on successive nights?
The Florin still needs more bath
