A photo of the back/mark will help as they do make fakes of this piece. $100 isn't out of line for this imo if an authentic piece. Here is one that sold attached to a cap w/ another pin. The value of this auction was that pin. The cap was probably worth $50 and the 1st. Lt's bar maybe $10 tops. WWII Overseas Hat Cap 5th Bombardment Group Di Crest B17 Pearl Harbor VETS | eBayI'm pretty excited about the watch fob though bc I need one to convert my pappy's service watch into a lapel piece and now I don't have to pay a whole lot for it. Also, I know that the one piece (skull) KIAI O KALEWA is from WWII. The only comparable piece I can find is on worthpoint. So it's likely a rare(r) piece. Any help would be greatly appreciated.
