Cleaning Copper coins
A really simple yet extremely effective method of removing tarnish from copper coins is to use a combination of “Salt and Vinegar”. It is really miraculous just how well it works, and just how fast it works! We would recommend white vinegar for the best results simply add some to a container and sprinkle some salt in then add the coins. After a minute or two stir the solution with the coins in, and remove and rinse. They will come up like brand new, this is more a technique for more modern coins as most ancient coins are bronze. However it is a technique that will work to a degree on some ancient coins as it really does depend on the composition of the metal the coin was made out of. Don’t expect this to work on your crusties but if you have fairly modern copper coins it is a fantastic way to get great results.
