Your ancient coin has already survived a few thousand years, but that doesn't mean it doesn't need special care. Your ancient coin has been expertly and meticulously cleaned, except for gold coins which are usually in bright condition when found. Most coins are found in caches and a build up of dirt and oxidation has been carefully removed to restore the coin to its original glory.
Avoid exposing your jewelry to harsh chemicals. Chlorine causes chemical reactions that can damage your coin. Salt from sea water can also speed up oxidation. Removing your jewelry before you swim is a best practice to ensure your coin remains beautiful.
