Dear GROCK:
MIght be a 1954 Birmingham mark but I cannot read the initials of the maker. Can you repost a little clearer?
You didn’t say what the mark was on but 1954 was the last year of operation of these medal and. button guys:
Doesn’t seem to be any clearer. Anyway the hallmarks are as I first read them and the maker’s name requires cleaning and photographing so you can read the three letters. At that point you can probably read them yourself and tell us if you care too. There are a number of similar medals on short snake chains attached to a clip fastener on Etsy to give you comparatives for price etc.
The general rule for anybody with blackened or otherwise obscured hallmarks or trademarks on silver is clean them before photographing. It seems sort of obvious but as the same suggestion has been made over and over again on this site it bears repeating.
Cleaning, as opposed to polishing silver can most easily be done by investing in a can or jar of commercial jewellery cleaner generally referred to as “silver dip”. This stuff is not for the faint of heart as it is carcinogenic but it and an old toothbrush would get the job done. Others recommend washing soda and tin foil lined baths which also work.
For more info go to the top right of this site and search “cleaning” and you will come up with detailed suggestions and caveats
