Circ 1973:
The two endpoints of a lot line in the "middle" of a paved road.
These two are really annoying, DOT at the time these were set, sometimes set a ROW monument for ownership and another one for a "construction" monument when the pavement was shifted from the centerline of the ROW. I can't explain why they would do such a thing, but I occasionally run into them.
I'm just impressed that PK nails set in 1973 are still in that good of shape. Most of the time you go back a couple years later and they are either paved over or destroyed in some way. I did just recover two that I set in 1999 and thought that was a record.
As for the brass disks, at least they set something.
I have found a few over the years where the top was sheered off by a snow plow and the shaft stayed put.

We found a third one that matched the small ones, which was the original surveyor's survey (at least I think it was). So we held the little ones and drilled in 2" caps for them.
50 years in pavement that's been plowed each winter, that is impressive.
I don’t follow the point of this post. I see one nail in each of the first two photos and the last I see grass a fence and a small rock. Where is the pin cushion?
I see two PK or Mag Nails in the first one. and two concrete monuments and a large pipe in the third.

Yes, exactly.
The pipe is confusing, but there it is. If it was set for the original ROW, then everything is all wrong since the 1970's.
However, it does appear to be more of a goat stake. Digging into it all now.

Here in my fair city, at some time in the past, elevation benchmarks monumented with PK nails in a lead plug in concrete curb were established. While I have no original notes of exactly how or when they were established I believe this happened in the 1970's, and possibly earlier. My evidence is the age of the subdivisions in which these curbs exist, the parts of the city that were subdivided later and have no extant PK'd BMs, and the landmarks mentioned in the typewritten listing . An example can be seen here:
(Select any benchmark whose name begins with "P" followed by a number)
We undertook to inventory the remaining benchmarks a couple years ago. About 70 of the original 175 remain. Thing is, those that are lost are so because the entire curb is gone. We did not find a single example of a hole in the curb missing its lead plug, nor of any lead plug missing its PK.
I'm not a fan of PKs or MAGs as monuments. They do not usually last very long, because they pop out. But properly installed in sound concrete or asphalt the nail itself is very durable.
BTW, in the OPs example we have PKs paired with MAGs. It's not tough to figure out which is older. This is why I insist that PKs and MAGs are distinctly different things. One should not be equated with the other.
It seems there are more goat stakes, than goats...
