You shouldn't clean ANY type of coin with anything. Why do you want to clean it? If the coin has PVC or such there might be a way to remove it. I would suggest that you do a search here on CT for CLEANING and read what there is to read. Speedy
why would he clean it? maybe its filthy!! Coins get real dirty... avi400 - Try giving it a long soak in distilled water, that might help disipate surface dirt...it will not effect the coin at all.
