This month’s counterfeit, a fake Indian Head gold $10 eagle, is an
old “friend” of mine, one that I initially inspected back in 1981,
during my first year with ANACS.
It is a rather deceptive fake that can be missed by many
collectors, until you know what to look for.
While the coin has a number of counterfeit diagnostics, the
easiest to spot are all on the date digits.
A series of horizontal “tool marks” can be seen on the lower half
of each digit, strongest on the 9 and the first 1. Some additional
tool marks appear on the rim, directly below the first 1.
Tool marks are tiny scratches on the surface of a die. They are
caused by a sharp tool that cuts into the die, usually in an attempt
to remove a raised defect, or strengthen die details.
These incuse scratches on a die produce identical raised lines on
the coins struck from this die, and can be an excellent way to
identify a fake coin.
These diagnostic tool marks are important because no genuine 1911
Indian Head gold $10 coins exhibit this pattern of tool marks on the
date, only fakes.
Collectors considering the purchase of a 1911 gold eagle should
always take a quick look at the date digits.
Keep in mind that while the presence of these tool marks is a
guarantee that a given coin is a counterfeit, the absence of tool
marks does not guarantee that the coin is genuine, as many other fakes
of this date exist.
