This Birmingham 1939 fob were given out by E.P & Border High School Athletics Ass. for the 100yds in the same year. This one I like because it were made in beginning of WW2 and must have been shipped the same year to South Africa. The medal seems to have a mat/pitted surface, Would it have intentionally be put one and how? The sides and engraving are still shinny but the hallmarks also got this mat texture.
