I finished soaking that V nickel that I last found. I am really happy about the shape, you can read every letter of Liberty in the crown. I decided to try a Buffalo nickel as well and it was pretty much dark red like the V was. The second picture is after a week of soak, changing the vinegar every two days and giving a light brush with a toothbrush. It is weird but as the red leaves the coin, it turns the vinegar a blueish green, kinda cool. The red color of the coins really went away and left behind the dull grey coins that are in the second picture. I then used a dremel tool with a cotton wheel and a little buffing compound to bring it back to life and shine it up a little. It even helped hide my shovel mark a little bit lol. I know that a lot of people are against cleaning their coins because of value, but I'm keeping these for my personal pleasure and wouldn't do it to a coin of great value. It is just so it is easier for me to see and share them. Hope that this helps for anyone interested in cleaning old nickels.
