Last week i went through some of my stuff. I decided to seperate some toned coins, some of which i aquired here, and clean them up. I never had any desire to do this previously , but was curious as to the efficacy. I more or less followed a 'silver slayer'? video on theirtube. Works a farkin treat. I know people talk about the charm of an old toned coin but clinky + extra shiney is great too. I dont get into numismatics yet, possibly i should have left the prospector, but yeah...something very satisfying about cleaning up an old coin. The 2oz kook was filthy.
