What Do "OM" and "NM" Mean?

Often in an eBay listing title, you will see the terms "OM" or "NM" in a listing title. This is what they mean:

  • NM means "no monograms" are found on the piece(s).
  • OM means "old marks". You often see this when an old Gorham piece is being offered. Gorham changed the information it placed on the backs of forks, spoons, etc. in 1950. If a seller places OM in the title, it probably means the Gorham piece(s) being offered were manufactured before 1950 and have the old Gorham hallmarks.

N.M. can also means Nathaniel Mills if it is combined with the appropriate English Hallmarks (i.e. Anchor, Walking lion & Letter depicting the year manufactured.

Nathaniel Mills was a designer for Birmingham in the 1800's.
