I have an old eight reales coin and noticed very recently that it had some verdigris in the obverse side.
I was wondering if anyone can recommend a professional coin cleaner as I have no idea how to clean coins and am afraid that cleaning it myself would ruin its value.
to CCF, don't clean it until the pros here chime in on this,o.k.? There is a member here that sells his own cleaner but I can't remember who, sorry. John1
8R coins are silver; chances are if you're looking at a greenish discoloration on the coin it's PVC damage from how it was stored rather than verdigris. The coin needs to get into an acetone bath. Do a Search on this Forum for "acetone" to find out how; acetone needs to be treated with great care but it will not harm a silver coin in any way.
