Cleaning Solution For Coins

The following thread is the best advice for getting gunk off of a coin. Our member BadThad has a background in chemistry and has given us this information:

If none of the above work anf you choose to use E-Z-EST, then see if you cannot find a common, melt value coin or two to practice with. A dip should only take a second or two, followed by a thorough rinse with water. More dips/rinses may be needed, with the idea being to stop making dips before the E-Z-EST strips away luster and makes the coin look flat and lifeless (over-dipped).

Thanks for the opinions.

I never considered cleaning coins. I learned from Earle42's referral to BadThad that there are proper ways to conserve a coin.

I had a bad experience attempting to get accumulated crud off of old wheat pennies that had been stored in a whitman folder for years. I tried soaking them in acetone. When I took them out, they looked worse, and I assumed them acetone had dulled them. Perhaps I did not leave them in it long enough. Regardless, I learned a valuable lesson: my personal experience does not equal universal truth. Thankfully if we (I) and willing to listen to the experts, we will become better collectors.

To a 64 Kennedy Collector or someone just beginning their journey into Coins that would be a nice starter peice . It is in Rough shape but it has value beyond melt . Treasure it . If someone offered you 10$ take the $ unless you want it keep it . I'd keep if I was you . Sure there's literally tons of 64's out there but nobody wants to let go . I'd keep it man . Try it clean it a little because at this point you arnt gonna do anymore damage . %

with BadThad. If anything, just acetone. Whatever it is, it looks like it's baked into the surface. Some like this environmental tarnish/patina look. A dip (IMO) would totally kill it.

Can we see the reverse? Whatever method you decide, post the after results here.
