<p>[QUOTE=&quot;Beena David, post: 3001778, member: 93417&quot;]Hey all! I have a question. I know why people in the coin world discourage the cleaning of coins - because the patina and toning is valuable and because some pieces are fragile and can be destroyed by cleaning. I have a question about cleaning for jewelry purposes, though. Recently, I purchased a couple of coins online to make into cuff links. A conductor I work with loves Verdi and once told us the story about the unification of Italy. During the struggle, the slogan was &quot;Viva Verdi!&quot; because V.E.R.D.I. also stood for Vittorio Emanuele Rei d&#039;Italia, who took the throne in 1861. So I found a few pennies engraved with this moniker and portrait from 1861 and I want to cast them in resin for cuff links as gifts. The coins are 15mm and made of 96% Copper an 4% tin. If I dip these into a solution of vinegar+salt and then rinse with water, will it eat the detail or just restore the color? Asking before I ruin it. Photo is of an actual coin I purchased. Any tips are appreciated.</p><p><br /></p><p>Thanks to [USER=10461]@lordmarcovan[/USER] for introducing me to this forum!</p><p><br /></p><p>[ATTACH=full]742811[/ATTACH] [ATTACH=full]742812[/ATTACH][/QUOTE]</p><p><br /></p>
