If it is "real" enamel, which is kiln-fired glass, laquer thinner won't

To remove real enamel, one would have to suspend the coin vertically and
fire in a kiln until the enamel ran off the coin. But, I doubt the OP
has
access to a kiln to do this.
Not to mention, I'm pretty sure gold melts before glass...
Ummm - how is glass enamelling done to gold or silver or copper, then?
(A.: the glass doesn't have to "melt" as such - it "fuses" and/or "softens".
Copper only has to be red-hot for this to happen to the enamel.)
Irrelevant to the question at hand, though. Reheating would *not* cause
the glass to "drip" off, though heating then rapid quenching in water could
well crack it off nicely.
