Définitions

anglais

A sticky oozing liquid that is actually the plasticizer that has bled out from a PVC plastic coin holder and lies on the surface of a coin. It is often coloured green (from the reaction of the plasticizer with the copper in the coin) but not often visible to the naked eye since it forms a thin coating on the coin which can dull the lustre and aid or cause corrosion of the metal.
