This is my first post, so forgive me for any errors I make. I found this object last year in the Gulf of Mexico, and just recently rediscovered it in my closet. Although I did have my bounty hunter detector with me when it was found, it wasn't the metal detector I found it with, it was actually my big toe! I had walked into the water until it was about waist deep to cool off, and along the way I kicked up what I thought was a rock or shell from the seabed. Thanks to the clear water though, I was able to see right away it was no rock.
I can't find anything out about this thing. Reverse image searching results in nothing. Research into many objects that fit the description results in nothing. Even endlessly searching for a match to the numbers on its side doesn't reveal a single thing. The only info I can give you guys to work with is the size, barely legible imprinted number, & the fact that it's a non-ferrous metal.
Size: 35-37mm long X 25mm wide
Imprint: (on right side of the cross from frontward perspective)
D 1179-67 C STD 9935 70
I'll attach a few good photos of the front & back along with one for a size reference.
If any one even has speculation of what this could be, what it could be made of, etc, please comment!
