I would think any use of lead plates as boundary markers would have died out as iron (a ferromagnetic material and thus more easily located with a detector) became cheaper than lead.

Well, fuck. My second thought was going to be cost concerns. Guess I should've gone with that lol I just don't know which came first, chicken or egg.

Lead holds up better in soil than most older ferrous metals. Also, it is easier to inscribe notations on lead plates. IIRC, there was a case years ago in southwestern Pennsylvania where someone dummied up some fake lead plates, "discovered" them, and fooled a local historical society.
