As some of you all know, I've been using Metal Detectors for years. To find the best "old stuff", in an urban area, you have to go to where "Urban Renewal" is taking place, where condemmed building are being razed. Here in Tulsa, that also means the lot gets scraped, removing the surface junk, and bringing the older, deeper, more desirable targets closer to the surface.
This also exposes some items that are highly collectable, but aren't made of metal, so you have to learn to "eyeball" them. I've trained my eyes to look for certain things, like marbles (color contract, reflective patterns, etc.), glass bottles, and even coins just laying on the surface.
As a result, I usually go around, looking at the ground where ever I'm at. Sometimes my eyes pick out a pattern that interests me.
This morning was no exception. I was outside, walking to the driveway to wait for the schoolbus. On the way there, there are lots of clover patches. My eyes picked up on a pattern that just wasn't quite right. I immediately stopped, and back up a couple steps. I started looking for what it was that triggered my curiosity.
Here is what triggered it:
This is only the second one I've ever found. The first was a couple years ago up in Michigan.
