🔎 UNIDENTIFIED Ideas What This Is

[McKinney_5900]

I found this a while back and finally tested it today. It shows to be copper by my best detector's polar display, which is very accurate. It measures .9 thousandth inches diameter and weight is 13 grams, about half an ounce, obviously hollow. The color and texture indicate oxidation or something, and it is very mildly un-round when I roll it. That oxidation or what ever it is is causing that roll friction. It was found here in north Texas somewhere. Its Vdi is 85-86. on my Manticore.

It's been too long since I found it to remember where I found it. Thoughts? I keep a lot of old finds. It is unique. A mini ball is solid, right?

Thanks.

I think you have a Native American "Game Ball."

This one reads perfectly as a copper. Those game balls are reported as clay.

Not all. Many are made of natural stone.

That wouldn't read solidly as copper though.

Ok either you wrote the wrong size.
The size compared to a dime shows that.

Just saying that .9 Thousands is smaller than....

Most human hair is One-thousandth of inch, or 0.001 inch.

Just because a detector says it is copper, does not make it so.

I flunked math twice. Here is it in a picture.

I read it wrong.
9/10ths of inch
7/8ths roughly
29/32nds

I completely trust my Whites V3i reading, using the polar plot, calling it copper. It sure isn't clay or rock. 2.5, 7.5 and 22.5 kHz all lay in the upper right quadrant.

I also pulled out my trusty Etrac just now and air tested this, and it nailed 12-45. Anybody knowing the Etrac at all knows that is a a solid, conductive number of quality.

I do see tiny glimmers, sparkles in the surface polished surfaces. Ok, nuff said. I'll leave it as-is, not cut into it. It has been fun ;-)
