1914 Date Guide
1914-D
Mintage 1,193,000 from only four known dies (about 298,250 coins per die on average). Classic Denver key — added mint marks and date alterations are well known.
Diagnostics in this package come from Chuck Daughtrey’s die study (Keys to the Lincoln, 2018). Mint marks were punched into working dies by hand until 1990, so position (and often tilt) separates dies. Overlays against fixed design elements such as the date make those differences more obvious and helpful in attribution to die and determining counterfeits. Measurements between the closest point of the middle date digits and the mint mark help confirm which die struck a coin.
Study sample: 261 different 1914-D coins. Relative frequencies: #01 very common (~30%), #02 very common (~33%), #03 common (~26%), #04 scarce (~10%).
The famous lapel die crack on Die #03 was once treated as “the” genuine marker — three other dies also struck genuine coins without that crack. All images in this study are courtesy of PCGS Coinfacts.
Known fakes & alterations
Key and semi-key Lincoln cents are the focus of authenticators and counterfeiters alike. Common alteration methods include:
- Adding a mint mark to a common Philadelphia issue of the same date (for example, turning a 1914 into a 1914-D).
- Scraping or altering digits of a common date (for example, turning a 1944-D into a 1914-D).
- Copying genuine coins by spark erosion or soft-die transposition.
Crude alterations usually fail under close study because device details and mint-mark character are wrong. Matching a coin to one of the few known genuine dies for the issue is a powerful authenticity check. When in doubt, use a trusted third-party grading service.
1914-D is heavily targeted: added D mint marks on 1914 Philadelphia cents, and altered 1944-D dates scraped into “1914-D.” Match to a known die (and die-state markers where present) before accepting a raw coin as genuine.
