Got this today at a yard sale, it was in a jar of old buttons, it is brass about size of a dime has the letters ABC some sort of collar brass but any help on what the letters stand for would be appreciate
Thank you for the responses. No manufacturers mark Most likely a Lapel Pin rather than a button. Non dug item, in with a jar of buttons plus some 40's & 50's stuff. from a Yard sale in Hedgesville Wva
