I found this YouTube video on another forum. Has anybody tried any of these methods and, if so, was it successful? http://www.youtube.com/watch?v=7sJSwKe5Ev8 Thanks.
I remember seeing that video a while back. The only method I tried was the eraser on a scrap maple leaf. I used a "magic rub" eraser, they are by far the softest and easier on the coin's surface. The slight friction still caused light hairlines on the coin.
It was important to hear the disclaimer on using his method on collector coins. Most people who have a procedure never address that. The fact he stresses it for bullion use only, sets him apart from many others.
Thanks for sharing this. I haven't tried any, but at some point may try cloudy ammonia on some of my wildlife series. I don't think the jewelry cleaning pad or the eraser method are worth it because you're damaging the surface of the coin even if only slightly. It probably wouldn't grade very well after that.
To be fair on the coin cleaned with an eraser leaving scratches could have been they were there un seen before the coin was cleaned. I find an eraser as soft as it is could do little or no damage to a coin. Ive cleaned many coins that way and dont see where there is a problem. When you see 1700 coins in worn but good condition think about how many times it was dropped or how many different objects were placed in ones pocket with the coin before it made it into your collection. Dont believe rubber would harm it much if any.
