<p>[QUOTE="Ralph Mlaska, post: 3332287, member: 101033"]I use a 10 to one vinegar peroxide solution , works well to restore the date. often a bonus of most to full horn. 24 hours in the solution, most likely if no date comes out your not going to get it, you may try another 24 hours . For that pasty white look use a dab of nonabrasive tooth paste and a soft tooth brush , care full of the date. Call it what you will , I call it preserving a coin. Having done this any many times I have over a 90% success rate. Understand what you are doing working with a metal alloy .750 copper .250 nickel. in the short term the solution will not attack the copper but remove micro layers of the nickel. thus if there is enough copper in the date you will retrieve it. don't try to enhance it after you have the date. You will lose it forever! because I do so much of this as a hobby , past time , I'll soak the coin in a cheap acetone ( finger nail polish remover) works better if you do this cleaning one step first because it allows your 10 to 1 solution to work on the coin not the years of accumulated ( Body acids) filth all old circulated coins have. just a foot note.. that filth on those coins over the years eats away at the coin.. so much for the die hard purest don't clean the coin thing. Just don't use an abrasive that will alter the coins. there it is my 2 cents worth![/QUOTE]</p><p><br /></p>
