<p>[QUOTE=&quot;Conder101, post: 844272, member: 66&quot;]A nice long soak in nitric acid is your only hope, but like Dutchman said you will probably we left with a depression where the solder was.&nbsp; But that might be less objectionable than a coin with a lump of solder on it.&nbsp; (The coin will also possible have a brighter gold color from the acid removing copper from the surface of the gold.&nbsp; One way to avoid that would be to dip the coin in wax first, then scratch the wax off the solder so it is the only thing exposed to the acid.&nbsp; You may have to run a couple of experiments first to make sure the acid doesn&#039;t affect the wax.)[/QUOTE]</p><p><br /></p>
