That had to be in 1982, which was quite some time ago. I have no idea what it was but I know it was found on Lackland AFB, in San Antonio, TX. I have found so much since then, who can keep track?
My first was a 1942 Walking Liberty half. I still get a thrill everytime I think of that moment when you first see that glint of silver!!!!!!
Good luck to all
