Age of Armed Forces Signal Corps pin and other mysteries?

[Geologyhound]

I found this US armed forces Signal Corps pin perhaps 30 feet from where I historically found an 1890s barber dime. I can’t find any information online to indicate the age, so any help would be appreciated. All the modern ones appear to have a smooth background, are domed, or don’t have a raised rim. Unfortunately, there does not appear to be any markings on the back. I’m not even sure if it’s supposed to be a collar pin or an oversized cufflink. It almost looks like the back piece was made to screw on, but there is one tooth – perhaps to keep it from shifting against the fabric.

The little fleur-de-lis piece was found in a different area of the site. It rang through loud and clear. I had to dig under some large roots for it, so I am not sure of the exact depth, but it was about 10-12 inches deep. I was a little flabbergasted that I picked up something that small that deep. There are two little knobs on the back so it must’ve been affixed to something. There are no markings on the back of this either. The only coin I found for this day was out in the middle of the woods and was a 1960 Lincoln…

Does anybody have any idea what the double sided ring thing might be?

Double sided loop thingy is part of a chain link from an old well pump.

Fantastic, thank you!

According to this webpage, the screw back is from 1937 to 1943. However the collar disc itself is the 1921 to 1926 variety. It is a single pin type which generally meant state or militia. So someone lost the original back and got a newer replacement before losing the whole thing.

1910-1926 screwback with a concave screwback, 1926-1937 screwback with a flatfaced screwback. Note that both are the textured brass with raised edge while the 37-43 is not textured, it is flat with no raised edge.

If I’m understanding you correctly, yes this face is definitely the 1921-1926 variety with the textured surface and raised edge. However, the screw nut appears to be incorrect for this face. The nut definitely appears to be the 3A variety (1937-1943) from the German dagger website. The nut has the ridges around the rim and the larger raised circle around the hole.

There are no photos of the screw back on the insignia he found so that can not be determined. My id is based on it being one of the two raised rims. Just pointing out the way to tell which raised one is that older one has a concave screw button while the newer raised insignia has a flat based screwback.

Sorry, I had it on angle in the first post so the tooth would be visible. Please see attached.

Type 3a 1937-1943 Screwback while the disc with raised edge would be 1926-1937 from what I can see in the pattern on the disc. I know that in 25 years of active army we would often salvage one piece of brass to fix another. As a sidenote the last brass they shows the disc is flat with a double prong screwback (which allowed the disc to be seperated from the branch (such as signal) so it could be polished. We would use a hand drill to spin/polish the brass disc and polish the branch portion of the insignia by cloth/hand using a product called Brasso). They still make and use this for todays army dress unforms.

The 26-37 discs appear to have square dots in a diamond for the background, whereas the 21-26 just seem to have a whole bunch of round dots in the background. Based on that, this one would definitely appear to be the 1921 to 1926 variety (with the newer screw back).
Thank you very much for your help!
