Most survey marks are not of interest to anybody other than surveyors,
much less tourists seeking to take them as souvenirs.  There are only a
few places such as Cameron's Corner, or Four Corners in the US, where
theft would be a problem.

If anyone wants to steal a National Geodetic Survey marker, the NGS
