Well, I guess it's better to have no data than to have the wrong data.  My favorite wrong marks have always been the three which were carefully reset from marks number 5, 8, and 12 (possibly county or USGS numbers?) and new NGS data sheets made.  The trouble was that those  5, 8, and 12 weren't in the NGS data base, and the resets were calculated from 5, 8, and 12 in another county so they were most of 100 feet off in elevation and scaled coordinates maybe 60 miles off from where the To-Reach took you.  At least one  (Geocaching) (NGS aa3904) would be a really nice location for a GPS mark.

Huh. D'you know who tried to do the reset? Seems like that's a big 'oops'..! :D
