Any of you smart guys know anything about those?
Daughters bought a ring from a charity shop for pennies, and later found that t had hallmarks on it.
Not sure if it is gold, but it is pretty heavy and looks way too good a quality to be just plain metal.
There are 3 hallmarks: the letter "M", a circle with what looks like a swan (or a duck) in it, and another circle with what could potentially be the letter "C"

Any idea anyone?
