<p>[QUOTE=&quot;medoraman, post: 982540, member: 26302&quot;]Well the article I linked showed natural nuggets in their test sample ranged from 86.8 to 99% pure gold. Not completely &quot;purified by nature&quot;. I have read how you purify by lead as well as mercury. I have purified gold myself using mercury on gold dust. If you read further about mercury refining it will show you that it is not completely purifying the gold, traces of other metals remain, as well as the mercury itself. In nature, yes, gold is found more pure than most other things. BUT, the first coins were electrum because that is the natural form gold was found in there, and its extremely common for silver to be found with gold found in nature.</p><p><br /></p><p>I do not think we should take Pliny&#039;s word as to the scientific correct purification levels of gold they could achieve. We have it already, with the article posted, stating they were able to achieve .99 pure for coins they intended to be pure gold. It was quite an accomplishment, but not .9999 let alone 1.000.[/QUOTE]</p><p><br /></p>
