I saw it once long ago in a book on money, but cannot remember it and have never found it online.

    "Watermark" is the only obvious single word I can think of. – Hot Licks May 15 '15 at 20:01
  • True, but in a broader context. The word I seek is very specific to numismatics. It's not a word with broader application. It's an unusual word, not one I'd ever run across before. – docwebhead May 16 '15 at 17:29



1 The process or action of proving or showing something to be true, genuine, or valid:
the prints will be stamped with his seal and accompanied by a letter of authentication

the authentications were both carried out by the Investigation Bureau of the Ministry of Justice

  • Thanks, but no. It is a specific term with no other applications. An unusual word I had never heard before and haven't since. It is narrowly concerned with only monetary authentication. – docwebhead May 18 '15 at 15:14

If you want to indicate the measures that are aimed to stop counterfeiters, security features is the term you are looking for.

It is stretching a bit but possibly hallmark fits the bill.

  • That's a good phrase, but it encompasses more than anti-counterfeiting technology. I'm seeking a specific, single word. It exists, I just can't recall it. – docwebhead May 15 '15 at 14:39
  • Maybe this reference helps: moneyfactory.gov/anticounterfeiting/securityfeatures.html – Bookeater May 15 '15 at 14:41
  • Ha! I actually read that site yesterday, which brought the current question back to mind. A good read, but it doesn't have my word. – docwebhead May 15 '15 at 14:43
  • Duh. And verification mark is two words as well...It is now stuck in my mind as well. Be assured I'll post in case it pops up later... – Bookeater May 15 '15 at 14:56
