Experimenting in coin brightening. Heavily circulated coins.

experiment please first, I think 9v is pretty strong. only took 1 minute for this setup. Don't forget to post your experience. GL, OH and don't forget to rinse in filtered water!!!
Yup me too, patina is nice on silver but copper is just UGLY, IMO.
Yeah not too much to like about that cheap zinc there's some Nickel in it though if it makes you feel better. And hey don't forget negative to the coin do not reverse the polarity you'll ruin your coin.
Hey Jeff, Yea I tried with and without, you get different effects. The amount of iodized salt I used on the first one was tiny not even 1/4 tsp per cup. Without the salt tends to get very coppery. Plus I rinse well. I'm confident the result is locked in but if it changes I'll post here. Sorry I retract the coppery effect... That happens with the vinegar. I'll post a pic of elec with no salt...
I did this one with heat first, Yikes!!!
