<p>[QUOTE=&quot;SeptimusT, post: 2971331, member: 91240&quot;]It sounds rough, but before trying electrolysis, I’ve had some success laying coins in a blob of Elmer’s glue and then ripping it off. This only works for coins with hard mineral deposits. It won’t remove anything that electrolysis won’t, and I’ve actually managed to preserve fairly decent patinas this way, although it was slightly uneven. The only time it did real damage was when the coin turned out to be riddled with bronze disease. My experience is limited, but archaeologists do far worse things sometimes. That’s where I learned this. Before and after:</p><p><br /></p><p>[ATTACH=full]729000[/ATTACH][/QUOTE]</p><p><br /></p>
