Here’s several 1914-D Lincoln Cent Counterfeit and altered coins.
The above 1914-D is a struck counterfeit and has the wrong mint mark font, no defining die markers and the die surface was altered to hide any imperfections.
This counterfeit was purchased in the 1970’s by a collector so it’s not new version. I personally tried to remove the mint mark and didn’t see any evidence it was added.
Below is an example of what an authentic mint mark should look like.
Here’s another 1914-D Lincoln Cent struck counterfeit that also has an incorrect mint mark, wrong placement and has sustained some environmental damage from extreme heat.
This is a 1944-D Lincoln Cent modified to look like a 1914-D.
A true 1914-D was struck with certain die characteristics, and if two or more of these are not present then it’s most likely a fake. First, notice the D mint mark on the authentic version and compare it to the fake, the D will have more of a “boxed” appearance and be angler inside the “D”.
Second, near the third fold of Lincoln’s shirt where it meets his over coat, there should be a die crack connecting it to the rim. Third, a true 1914-D will not have the designer initials V.D.B. under the shoulder, the designer initials where not placed on this area of the coin until 1918.
If a seller refuses to give close up photos of these areas for a diagnostic then do not bid on the coin. It’s best to buy a graded and authenticated version until one can learn how to identify this rare date.
Many fakes and altered 1914 D Lincoln Cents abound so collectors need to be weary of raw coins and seek advise or buy already authenticated key date coins.
