HTx New Member United States 24 Posts	Posted 03/25/2019 4:40 pm Hello All I came into some coins that are in need of some cleaning. Not sure how best to do it. Many of the coins I came across resemble the six below. Left to right: 1945 Ven silver 1944 Ven silver 1874 Costa copper 1899 Nicar nickel 1946 Ven silver 1896 Ven nickel 1909 Argen nickel 1943 Colom copper I know that coins should not be cleaned but I can't store them in this condition. Are any valuable ? I can't say for sure, probably not after all the green crap is cleaned off. Thanks for any comments htx Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 73898 Posts	Posted 03/25/2019 5:05 pm The safe way to clean these without harm I know of is a 100% pure Acetone soak and Verdi-Care. Errers and Varietys. Report this Post to the Staff
HTx New Member United States 24 Posts	Posted 03/25/2019 5:35 pm Hello Errers Thanks for the reply. How long to I soak them in acetone? ( hours? days? weeks? ) Can I soak many of them together at the same time in the same container? Or should I separate the copper and silver and nickel into separate containers? Once the green is no longer visible, can I store these coins with my other existing coins in the same container or is the green still contagious? Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73898 Posts	Posted 03/25/2019 5:51 pm I usually soak them for four hours or more. I would separate the coins, so they don't end up getting gunk from other coins. It won't take the green off, but it will take any dirt, crud, or verdigris off. You probably would want to use Verdi-Care for the green stuff. Errers and Varietys. Report this Post to the Staff
mikem007 Valued Member United States 318 Posts	Posted 03/25/2019 6:47 pm Test on one coin first and if you get the intended results, do the rest. One problem I experience often enough is that the dirt layer is actually hiding a lot of stuff. You may not like what you see underneath. Whatever you do, don't scrub that coin with anything as you'll see those scrub scratches. You may not see scratches with your eye but once looked at under 5x magnification, you'll hate the end result. Report this Post to the Staff
jimbucks Pillar of the Community United States 4691 Posts	Posted 03/25/2019 7:26 pm If you put in acetone, be sure to remove before it evaporates because the junk will redeposit. I would think 20 minutes would be adequate. Why not try mild soap and water first? Report this Post to the Staff
