Why would I be interested in cleaning a coin? Let's see, dirt, oil, grease, other sticky substances that detract from viewing complete coin. I am not an advocate of dipping and other extreme coin surface alterations, but do believe that removing dirt and other foreign substances is acceptable.
A rinse in acetone followed by several rinses in de-ionized or distilled water, and air drying will get rid of oil, PVC residue and organic matter, without damaging the surfaces. Each and every other cleaning/chemical dipping method known to man removes metal and alters the coin surfaces.
I dont want to clean all of them, but they have grime in the letters and the low parts. Is black dirt desirable?
Hi Mac, I think the word "CLEAN" is what got this thing going, however there is a safe and excepted way to remove dirt and grime from a coin in my opinion and it is as stated by Roy just be careful and take your time. Bruce.
I think you are referring to the black toning on silver coins. YES it is very desirable. I highly recommend you keep the coins as they are. - Jake
Hi no good at grading but I can tell you that they all look fine :smile Looks like some nice purple toning on one of those cents :thumb: De Orc :kewl:
Boy-O-Boy, am I glad you asked the question before acting on your own... Don't clean those beauties Take care Ben
