Just Carl, Thanks for posting this. I am really new at coins. I have a lot of circulated walking liberty halves that have black grime. Pursuant to what I have read in the literature, I religiously avoided doing anything to them. Ciould I gently use a swab, at any point between the water and acetone, or just dip?
cowdog, be careful of what you read, especially if Carl writes it. Many times he is joking and you should absolutely NOT do as he suggests. What you have been reading is the best advice for those without experience - leave the coins alone.
thanks administrator! some of these were so grimy they marred my cheap harrris folder, and required handwashing after pulling them from the bags. It is a sore temptation to want to do something!
Well handwashing them is definitely not a good idea. Improperly cleaning a coin can cause it to lose up to 80% of its value.
GDJMSP, I am sorry; let me try to word this better. After I pulled the coins from the bag, my own hands were very dirty. I did not wash the coins (Though I still want to!). I have dirty coins, smudges in my Harris folder, and clean hands!:smile
True I do joke a lot. Comes with old age. HOWEVER, I do believe in dipping really ordinary coins as noted in Acetone and distilled water. Nothing to loose and could get rid of some acidic items. Never wash of course. But a simple dip in solutions that do not effect metals will also not harm them. And as usual most people are excessively concerned about VALUE. Ordinary coins that have been dipped in such NON abrasive solutions can not change the value. The basic notation of not cleaning a coin is what is now normal. Coins as a rule should not be cleaned. But that too depends on what is considered cleaning.
That is only true to a point Carl. Even dipping in acetone, if done improperly, can be harmful to the coins. And that is why I always have a problem with such comments. If you are going to tell someone to do something, when that person has never done it before, then you should at least provide a full and detailed explanation of exactly how to go about it so they do not do harm to the coins.
take a pot dip the coins and stir lightly till well toasted no seriously i doubt giving instructions would work i think sometimes in hand demonstrations are best
Of course this is very true and more so for the safety of the individual than the coins. Coins can be replaced but damage to eyes, face, etc may not be fixable.
Yes and no. My experiences in chem labs have been that very detailed instructions to younger people may not have sunk in completely. Naturally well monitored experiments by some are required. Just telling someone to try something is not really smart in many instances. What GDJMSP is rather explaining
