Hi aa battery, nice Mercury and other finds.
Why are your days coming to an end at Hammer Field? I see you’re up North, what about the other two places near you?
In three years of MD’ing I’ve only lost one thing that I know of. It was a Washington D.C. Transit bus token designed like the one you posted in your finds. I remember correctly, this was a common transit token design back in the 60, and into the 80’s. Most likely use now days too. What kind of token is the one you found?
