I've been going through some of my dad's stuff. During the war, he was with the 308th Airdrome Squadron. Their job was to move into a (more or less) secure area and either establish a new airfield or repair one damaged. Once operational, they moved on to the next. They ended up in Laoag, Philippines, where they repaired, refueled, and rearmed B17's, 24's, 25's, and various fighter planes based in the area. I can recall a couple of stories about ‘Pappy’ Boyington and the black sheep squadron.
The matchbook is from May, 1960:
I believe these shells were used locally as infomal currency. 
My dad once told me what they were called, and where from. Unfortunately, I don't remember either. I suspect Papua New Guinea, or Malaysia. Knowing my dad, it's likely he took them in exchange for US currency. There are 45 of them.
