How do I read the date on a worn coin?
Use light and angle
Worn coins often lose the detail near the date, but a low, angled light can reveal raised lines that flat light hides. Turn the coin slowly and look for shadows that show where the numbers were. A magnifier helps you separate a faint digit from a scratch.
Pay attention to where the date normally sits on that design. Many U.S. coins place the date in a consistent spot, so the faint marks in that area are often the numerals. Once you think you have a date, compare it with a reference image for the same design and year range.
- Use a steady, angled light source
- Try a 5x to 10x magnifier
- Compare with reference images of the design
- Avoid rubbing the coin to bring out detail
When the date will not read
If the date is too worn to read, you may still identify the design type from the portrait, reverse, or edge. Some coins are only worth a little more than their metal, so do not pay a lot for a coin you cannot identify. A local dealer or a coin club can give a second opinion.
Common mistakes
- Rubbing the coin with a cloth or eraser, which removes detail and value.
- Guessing a date from a faint mark instead of comparing with a clear example.
