I am a rookie shot glass collector and came across this cup. It is very small and the mouth is only a little larger than a nickel. I cannot tell if the monogram is a trident or a letter and if it is a trident, does it mean anything? I read the star on the bottom is the Spanish assayer’s mark but I cannot find the source of the maker’s mark. The cup holds 1/2 shot of liquid. If anyone can help at all I would greatly appreciate it.
