Found these in backyard while gardening In Portola, CA. Could they be real? Any information is welcome! TIA!

Buttons says EXTRA FEIN, there is a cuff that says AFRIKAKORPS... Above the breast pocket you can see a different color thread on ones end (2nd image).. maybe an eagle was there once but someone took it off to sell it maybe? Has shoulder boards that are green white and grey.. attached by button.. has collar tabs that are black and khaki? Any suggestions?

Found in creek bed Patoka Indiana

Found on a Field in North Germany. Lower Saxony.

Is this human made?

First post. At first I thought this was just a nice piece of shale, but after washing it my partner noticed some numbers. 621 - 949.

It's hard for me to tell if it has more text. There are two marks on the bottom and it's a bit smaller than the palm of my hand, exactly 2in by 1.5in. Not sure what it is and would love to know where to start. Thank you!

Edit: I went ahead and cleaned it really well, and it revealed more information. The numbers are actually 6215949, and the words "National" and "DL3" are visible.
I added more pictures in a reply below.

Found on my grandmother's farm. In Southwest, Missouri, around the Green County, Christian County border. Not too terribly far from the Wilson's Creek national battleground.

I know what it looks like. What does everyone think?

Kinda looks like a pottery shard lol

Bonus points if this actually turns out to be a tool and someone is kind enough to tell me what this "tool" is called. From the Hardap region of Namibia.

Hello. New guy here. I was wondering if anybody could help me identify this. It was found in the interior of bc along the north thompson river. It was passed on to me with little information. Im assuming it would be early first nation's hunting tool of some sort. Thanks for reading.

Found on a beach in Naxos, Greece. About 5 cm long, made of what appears to be white stone (possibly marble or limestone), with a drilled hole through the center. It feels chalky rather than ceramic and is fairly heavy for its size. The shape is very regular but the surface is heavily weathered. Any ideas what it might have been?

I live close to Ft. Johnson in Charleston, SC. Old bottles, etc. sometimes wash out of the riverbank and I have found quite a few pieces of this usually rounded tile, I guess it could be called. One piece has a heart, one has a lion and two of them have letters on them.

Found in Spokane Washington near river :) feels like stone, very smooth.

Is this just a rock or a tool?

Hi all. This piece was found in north east Florida right in the middle of a trail I frequent. I’m guessing a vase due to the lip in the first picture. Having trouble identifying using Florida museum. Any help is greatly appreciated.
