The listing, 24 K gold plated quarter has ended.
2005 West Virginia quarter
has been gold plated, but not clearcoated.
To protect it from ever losing its gold, it should be clear coated with any clear enamel paint, but is totally show off able without the coating, just dont let a lot of people hold and rub on it. If you put it inside a coin holder, that will serve the same purpose.
I did the gold plating on this myself, so its a very thick plate of gold. I used it as a sample piece before I gold plated the actual part that needed the gold plating.
