<p>[QUOTE=&quot;coincidental, post: 3137390, member: 90860&quot;]Yes I&#039;ve got all the testing stuff the silver test was indicating very low amounts of silver in a yellowish result I&#039;ll have to do a magnified look at a test I guess. The copper was all over it and I used oxyilic acid as I heard it doesn&#039;t effect solid silver metal and for some reason a citric acid cleaner as one acid on its own seemed to stop working after a while so I had to swap every so often. And verdegris goes redish in acid I&#039;ve found although this coin looks like it&#039;s desolved back to the purerer copper now. When I was testing with the really strong acids for the Nobel metals I did get green from the &#039;red&#039; (coppery) deposits as such also which is usually a copper trait I think.</p><p><br /></p><p>Anyway:</p><p><br /></p><p>Great thanks that was what I was after I wasn&#039;t sure about leeching. But it does look like a flap I just don&#039;t want to lift it yet I guess. I&#039;ll do a specific gravity test next not sure if it will enlighten but worth a try... And I&#039;ll go over that info. properly... It&#039;s all about learning anyway <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> .
