If you find old coins while hiking or playing in the dirt, there are a few ways to clean them and preserve their value. The most common way to clean old coins is to immerse them in a bowl of water with a little dish soap. You can also use a toothbrush to scrub the coins if they are dirty. Be sure to rinse the coins well before storing them. If the coins are very dirty, you can try using a vacuum cleaner with the hose attachment. Be sure to use caution, as too much suction can damage the coins. Finally, if all else fails and the coins are extremely dirty or damaged, you can try boiling them for 10 minutes. This will remove any dirt or residue and may restore some of their original value. ..
