Should you clean old pennies? Not recommended. It makes them look like copper but you are ruining it’s value.
I can tell you that vinegar and salt should not be used to clean coins. While these household products may seem like a convenient and inexpensive way to clean coins, they can actually cause damage to the coin's surface and potentially decrease its value.
Vinegar is acidic, and when mixed with salt, it creates a solution that can corrode the surface of the coin. The acidic solution can eat away at the metal and remove some of the patina, which is the natural tarnish that forms on the surface of older coins. This can result in the loss of details on the coin's surface, and in severe cases, even create pitting or holes in the metal.
Furthermore, the salt in the solution can act as an abrasive, which can scratch the coin's surface and cause further damage. This can be especially harmful to coins that are made from softer metals, such as copper or silver.
