Are these items related to the Knights of the Golden Circle?

I found these items on my land, along with hundreds more while I was digging a hole, one of the rocks I posted has four holes at the top, and I have several more that are very similar...anyone think they could be related to the KGC? Let me know please, thanks

Hard to tell, since you moved them from original location, you may never know.
