Hi I'm new to coin cleaning and I have a small Greek (I believe) coin that after removing the dirt has a very even light green
patina. If the coin is wet and with
side lighting you can a fairly clear outline of a
bust on the
obverse and some detail on the
reverse. However, once the coin is dry it is almost impossible to see anything. The coin is quite worn but if I could figure out how to maintain the contrast I'm sure it could be identified. Is there a method to increase the contrast by darkening the overall
patina (I've read about the JAX products for doing this)? It seems that a process like inking and wiping a plate for
intaglio printing might
work but I don't want to ruin whatever chance I have of ID'ing this.
Thanks for your
help.
