The 1909-S VDB Lincoln has always been the key date coin in the entire Lincoln cent series, and it remains one of the most popular coins in numismatics.
Since the 1909-S VDB Lincoln cent has always been highly desired among collectors, it is notorious for attracting counterfeiters. There are many fake 1909-S VDB Lincoln cents out there in the market and at PCGS, we have seen many different types of fakes.
When examining the 1909-S VDB Lincoln cents, some of the diagnostics PCGS graders look for are in the area of the "S" mint mark. First of all, the 1909-S VDB Lincoln cents were struck with four different obverse dies. The four known dies have four different mint mark positions and to the untrained eye, they can look very similar.

These are just some of the diagnostics to use when examining 1909-S VDB Lincoln cents. If your coins look different, it is highly recommended that you send them to PCGS for authentication.
