Gold - Sigma Metalytics PMV SM1601 User Manual

Database Options Explained
The PMV Original's database covers a wide range of alloy options. It's
important to select the right alloy setting for your sample. Below is a list
of the available alloy options and what they mean.
Gold Pure
Gold samples that are 99.9% or higher purity. This includes 99.99%
and 99.999%. These purities are sometimes written as .999, .9999, and
.99999.
91.7% 22k Bal Cu
Gold samples that are 91.7% gold with balance copper. These samples
are sometimes advertised as 91.67% gold or 22k gold. Balance copper
means that the other 8.33% in the sample is copper.
90% Bal Cu
Gold samples that are 90% gold with balance copper. Balance copper
means that the other 10% in the sample is copper.
Gold Eagle
American Gold Eagles are 91.67% gold, 3% silver, and 5.33% copper. The
American Gold Eagle has a very specific alloy used only in this type of
coin. Even though American Gold Eagles have 1 ozt of gold in them, they
are actually 91.67% gold with silver and copper as the balance metals,
which is why they weigh more than 1 ozt in total.
Gold Maple Leaf
Canadian Gold Maple Leaf coins are pure gold (99.99% or .9999). Some
special edition Maple Leafs are .99999 pure but can still be tested on
this setting.

Ducat and other historical gold coins.

Asian markets.
