Avoid – cleaning lowers the collector value.
With these answers we do not recommend the ultrasonic cleaner, so there is no how-to.
Pick your cleaner to see if it fits, which setting to use and what its manual says.
Why
Most coin experts advise against cleaning because it removes the patina and lowers both grade and value. A cleaned coin cannot be restored.
Do this instead
- Leave the coin as it is
- Ask a numismatist if you are unsure
