One of the more valuable resources ANACS has in its library is a
series of counterfeit reports issued by the International Bureau for
the Suppression of Counterfeit Coins.
This set contains more than 400 reports on fakes from all over the
world, and includes diagnostics for every piece listed.
Since the IBSCC reports cover a wide array of fakes, when we
encounter a fake world coin that is not listed in the series, we
document it for future use.
Such is the case with the counterfeit Great Britain 1893 gold £5
coin illustrated here.
Judging by the damaged rims, this coin was probably in a jewelry
bezel at one point in its past. This by itself is not an authenticity
diagnostic, since both genuine coins and fakes have been turned into
Being in jewelry does tend to damage the coin’s surfaces and
remove any remaining luster, which makes authentication a bit more difficult.
While the coin’s finer details are fairly sharp, the bottoms of
the peripheral letters are curved and rounded.
This effect often appears on counterfeit gold coins, and indicates
a coin struck with insufficient edge pressure.
This effect can also be seen on genuine error coins, such as
off-center, broadstruck or incomplete planchet pieces.
In each case the retaining collar does not exert proper pressure,
and metal flows outwards instead of up into the lettering.
The other diagnostic for this fake is a group of diagonal dents in
the field behind the horse’s hindquarters.
These “depressions” were contact marks on the genuine model coin
used to produce the fake dies.
They were transferred from the model coin to the dies, and will
show up on all the fakes struck from these dies.
I would like to extend special thanks to collector Theo Gould for
graciously agreeing to share this counterfeit with the numismatic community.
