Fake Mexican 1931-Mo 5-centavo coins turning up
- Published: Aug 22, 2014, 4 AM
The flood of counterfeit coins from China continues to expand.
After spending years producing fakes of silver dollar-sized coins like U.S. Trade dollars and Morgan dollars, Spanish Colonial 8-real coins, Japanese silver 1-yen pieces, and 20th century China Republic dollars, we are now seeing fakes of better date copper coins from numerous countries.
The fake shown here is a rare date example, a Mexico 1931-Mo 5-centavo coin.
Worth the effort
The Standard Catalog of World Coins lists prices for this coin at $1,500 in Extremely Fine and $4,000 in Uncirculated, making it well worth the effort to counterfeit.
The downside to faking rare issues is that these pieces are given extra scrutiny when being bought and sold, and taking a close look at this counterfeit gives it away.
It appears that a genuine 1921 5-centavo coin was used as a model coin.
The 2 in the date on the genuine coin was altered to a 3, then counterfeit transfer dies were produced from the altered model coin.
When you look at the 3 in the date on the fake, the upper half of the 3 has a natural look, while the lower half appears to have been hand-cut, with a clumsy appearance.
Fuzzy details, sharp edge
Additionally, the design details are a bit fuzzy under magnification, whereas the edge of the coin is much too sharp for a circulation strike.
The fuzzy details are typical of a medium-quality transfer die counterfeit, as the transfer process tends to cause a loss of sharpness, but this diagnostic requires good lighting, a quality magnifier, and for most collectors, a genuine coin for comparison purposes.
The sharp edge results from the higher striking pressure, counterfeiters often use to counteract the loss of finer details.
ANACS authenticators have learned over the years that this type of fake rarely shows up in small numbers — the counterfeiters tend to strike hundreds, if not thousands, of pieces.
Collectors need to be on their guard with this date, as well as any other issue where the cost of a fake die and 20 cents worth of raw materials can be turned into a major money-maker.
