Counterfeit Detection: Pass the Test
Posted on 3/10/2010
In high school history class, a student asks his teacher, "Do I need to memorize dates for tomorrow’s test?"
The teacher replies, "No dates."
Encouraged, the young student goes home and studies hard, following the teacher’s instruction. The next day he fails the test. Miserably.
Of course, the teacher had not told the student there would be NO dates on the test, but that he should KNOW dates. For aspiring counterfeit detectors, this instruction should be made even more clear: K-N-O-W dates!
Dates are very important areas to examine because they are unique to a particular coinage issues. The position, size and shape of the date should be the first elements examined when attempting to determine authenticity (unless better diagnostics are known for that coin). Often a misshapen or wayward digit is confirmation that something is amiss.
While this advice might seem to apply primarily to altered date coins, it is just as important for die-struck counterfeits. This 1895-O Morgan Dollar is a die-struck counterfeit recently made in China. It is of the correct weight and metal composition of an authentic coin. It is made from transfer dies and this coin would deceive many collectors.
By looking at the date under magnification, the coin immediately falls apart. Raised blobs of metal can be seen surrounding the 5, most prominently at 5:00 and 7:00. The metal flow is also suspiciously smoother in this area, dissimilar from the texture seen around the other digits. If you knew nothing else about this coin, those markers alone should scream, "not genuine."
The counterfeiter made transfer dies for this coin by using a model coin from the 1890s, replacing the last digit with a 5. While this reveals the counterfeiter’s methods, it also tells us something else. Coins of every date and mintmark combination can be made in this same fashion. It’s therefore important to remember that this rule always applies: "Know dates!"
