MichioKaku Valued Member United States 374 Posts	Posted 11/30/2015 1:31 pm Ok, so folks talk about "restoring" a Buffalo nickel by using vinegar. It damages the coin. However, vinegar reacts with the copper under the thick nickel coating and raises the copper, which raises the higher areas. My question is, would boiling your nickel in hot water for about twenty minutes do the same trick, since it would heat the copper under the nickel coating? * Moved by Staff to a more appropriate forum. * Report this Post to the Staff

CoinCollector2012 Pillar of the Community United States 8137 Posts	Posted 11/30/2015 4:52 pm Nickels are not like clad coins where they are plated with a metal. The copper and nickel are mixed together in the coin. I don't think that hot water would do anything but feel free to try it. Report this Post to the Staff
