<p>[QUOTE=&quot;physics-fan3.14, post: 3195539, member: 19165&quot;]In that case, that is an absolutely stunning example of what original gold should look like.</p><p><br /></p><p>For those who may be reading this thread but are unfamiliar with what I&#039;m talking about: this is what we refer to as &quot;green gold.&quot; You see it fairly often with Southern gold (especially Dahlonega, but sometimes Charlotte), less commonly on other mint&#039;s coinage. Basically, this coin is an alloy of primarily gold, copper, and silver. The gold content is tightly regulated, but the remainder can vary somewhat more. When there is a bit more copper than silver, you tend to get orangey or reddish surfaces. (An intentionally higher copper percentage gives pink or rose gold, such as the breast cancer awareness commem posted in another thread.). When there is a bit less copper and a bit more silver, you sometimes get this greenish hue. The silver and copper will tend to tone, whereas the gold doesn&#039;t - so the primary alloy will usually dominate the patina.</p><p><br /></p><p>When you see this greenish color, especially when combined with the very minor orange copper spots as seen on this coin, it attests to the fact that this coin is completely original. This is a very attractive coin, and a great example of the uncommon &quot;green gold&quot; look.[/QUOTE]</p><p><br /></p>
