How are coins professionally cleaned?
Рет қаралды 2,142
Жыл бұрынThe cleaning of coins are controversial. In most cases coins should never be cleaned. Many people recommend substances such as baking soda, salt, vinegar, lemon juice and a myriad of substances that can totally destroy all numismatic value. Jan Kleynhans is renowned Numismatist with several years of experience. He has developed a technique to remove organic material from coins without damaging the actual coin.

Well done I liked the disclaimer, normally I would normally never clean a coin, but I like the concept of preservation as opposed to cleaning. I bought a William and May Irish 1694 copper halfpenny online and was disappointed to find Verdigris on the entire rim. Last week I bought two IRL1959 error farthings the fada / over the E of Eire was touching, the seller through in two BUNC 1968 pennies but the reverse of one had slight Verdigris on it, I had to clean it off otherwise it would spread to the whole coin. but I made sure to clean the affected side only.

Thank you Peter. Yes, this has happened to me as well in the past. A photo does not always reveal the full extend of tarnish.

Very interesting. I know a guy who has been collecting for years and he always uses a ultrasonic cleaner?
