Curious to know as can't find too much definitive information on post lacquering appearance, especially of bronze.
The reason I ask is that I bought an 1866 penny in 2010 as a BIN from e bay, which the seller said at the time "showed signs of old lacquering". Because the coin was otherwise decent, probably about GEF, and had no obvious issues, I bought it for the £50 asked. It was then put away in my collection and largely forgotten about until today, when I read something about lacquering of coins, and was reminded.
Does anybody know what - typically - should be looked for to establish evidence of lacquering? Thanks in advance.
The coin itself is as shown:-
