Anyone think they can ID it this time around?

[Josh27]

Found this little object awhile back while vacationing in Florida. It was just under the sand in some shallow water. I posted it on here once before, but no one could determine what it exactly it is, or is used for. Most everyone seemed to agree though last time that it can’t be very old. (Considering there’s some sort of manufacturers # on it-but which yields no results.)
Since the original post I actually had it tested at a local coin shop, and their machine determined the front is roughly coated with a type of silver alloy, and that the back was mostly bronze (or brass, one of those..) They didn’t even know what it was! So, anybody have a wild guess? Or, better yet, has anyone seen one of these before?

There’s a few numbers/letters on one of the sides. I’ll upload a pic of that after posting this, but they are;

D 1179-67 C STD 993570

Size: 35-37mm long X 25mm wide

And here’s a picture of the serial/model/something number

Is there any gap under the circle on the back? Is the circle cone shaped? Have you tried to pop the circle off? How thick is it? Would like to see a shot from the side. Could it be a brooch? Bookmark? Bolo?

ETA: Now I see... The plot thickens... Hmm...

It just looks like a mourning pin missing it's stud IMO.

All of these sound like good, logical guesses. My first thought was a button of some sort, just missing the fastener. I’m just curious as to why that number on the side can’t be traced back to anything though. Not even a partial match.

looks sand cast

That part number on the side negates this object from being any kind of jewelry. Here is what you should be steering towards...

....I wasn't aware of the p/n at the time of posting. My Brother and I had careers in earth science, vapor deposition, composites, geological studies, mechanical engineering, think tank, DOE, DOD, EPA, H&S, NSF, blah, blah, BFD! Personally, I know this thing is used along these lines.....silver (plated?) On one side, bronze-brass or glass sintered on the cross side , masking around the back and sides , in a corner of the cross deposits lay, a detent "button" for orientation is on the back , the circle material needs identification and inside the circle is a (silver, incolnel? ) contact centered at the confluence of the cross and lastly an apparent part or manufacturer number that is uncommon.
We have been searching hydrogen catalizer, filters, sensors, igniters, batteries ect....to no avail. Next checking organic vapor analyzers (OVA)and , Hnu....non destructive gas testing .
Possibly , Josh knows of a "program" conducted in the area besides NACA/ post NASA like soil or air testing. Found at the shore is a long shot but thought I'd ask.

Edit....I believe the cross side is made of sintered metal similar to this...I further believe it is stained from use.

Edit..I'm not"out there" BUT , are there any nuclear power plants in n the area ? Found a partial number match but cannot access the manual.

Puts me in mind of a casting pattern, press it into the casting medium, remove it and pour the metal. The rough surface would serve to retain parting compound.
