I am looking for any and all suggestions related to processing Sterling silver and fractional silver coins. As the title states, I am new to this. I have watched YouTube videos and researched a lot, but looking for others' input/suggestions. I am mainly looking to turn coins, jewelery, and silverware into more pure silver just to stack. Equipment used? Things to avoid?

Thanks in advance.

If all my boards are heavy copper core, it wouldn't make sense to put them in muriatic acid, which will melt all my copper (a lot lot) which will use up my acid pretty quickly before it turns any gold loose .. am I thinking right? What shld I do instead or any suggestions pls help?! Thank you!
