Back at one of my old school sites tonight for a short hunt and I got a banging 39-40 on the Nox, no iron grunts to indicate some rusty iron deception. I knew it was too high for a silver dollar, but thought, "hey, maybe it's TWO silver dollars!" No such luck, but i was pretty happy to dig this tag from my home county up - and for some reason this era was aluminum so it survived pretty well. Now to clamp it between a couple boards to flatten it.
