Let's review. An ephelis, or freckle, is a type of macule, which is a small (up to 1cm in diameter), circumscribed, flat, and thus nonpalpable change in the pigmentation of the skin. By nonpalpable, I mean you can't feel it. Or more specifically, you can't feel any difference between it and the surrounding 'normal' skin.
The troy ounce is the standard silver price that you see on the t.v. 1 troy ounce = 31.1034768 grams or 1.09714 U.S. Ounces. It is usually just referred to as an oz.
1 Ton of Silver = $1 Million @ $31.10 / Troy oz. Silver price is hovering around $30/ troy oz, once Silver hits $31.10 / troy oz, Silver will cost exactly $1/gram, at that point the 1 Ton of Silver displayed above will be worth exactly $1 Million Dollars. Silver is not purposely mined, 80% of new Silver production is a by-product of Gold or Copper mining, this is due to Silver's recent low value compared to other metals.
