The 1964H Hong Kong 5 cents is the key date in this series. Though the coin was not released for general circulation, some examples survived and are sought by collectors.
Because of the small number of extant specimens, pieces can fetch hundreds of dollars each, making this coin a target of counterfeiters. Indeed, graders at Numismatic Guaranty Corporation (NGC) have noticed an increase in the number of fake 1964H Hong Kong 5 cents submitted for certification.

At first glance, the coin appears genuine. Nothing in particular really stands out, and it seems to be simply a lower-grade 5-cent piece. A less-informed numismatist might not even know it represents a particularly rare year and thus would not notice the numerals of the date. However, further examination reveals the true nature of this coin.
In the photo below, notice that the fields around the “4” are scratched and lighter than the surrounding areas, suggesting this coin was created by altering a more common specimen. The forger painstakingly moved metal on the coin’s surface and the last digit to create a “4.” The resulting abrasions are called toolmarks and are commonly seen on altered pieces.

If you are considering purchasing a coin that has a small design element (such as a date or mintmark) that makes it much more valuable than a normal example, it is important to closely study that area of the coin. Collectors also should be aware that contemporary Asian coins are among the primary targets of forgers. In fact, two of the top five coins on NGC’s list of most commonly counterfeited world coins are Asian specimens minted in the 1940s: a French Indo-China 1943-44 tael and a Vietnamese 1945 20 xu.

As always, numismatic items certified by NGC are backed by a guarantee of grade and authenticity.
