Silver and Flatware/What does the XX5M mean on the back

Hi Jim,

I inherited a 12-piece Tiffany and Co. English King pattern sterling silver flatware, 111 pieces, English King Mono D (1885, Monos M/T/C stamps) (TISENK1, Pattern # 1885) with specialty pieces e.g. serrated pastry server, 2 mdm cold meat serving forks, 12 long-stemmed ice tea spoons, master butter knife, 2 mdm vegetable serving spoons, gravy ladle, and a pie & cake server, and I was wondering what the small stamped mark on the back "Pat XX5M" means(I believe that's what it says. It's too small to read). And what the approximate re-sale value of this might reasonably fetch. Also, can you further identify this, or correct me with what I believe to be its accurate identity?

I don't know what the "XX5M" means. Normally, a year is displayed after "Pat" indicating the year in which the patent for the pattern was issued. I tried to figure out some Roman numeral that made since but could not.

The pattern does look like English King.

As far as resale value is concerned, I'm going to give you some calculation work to do. Look at comparable monogrammed pieces on For a working figure estimating what you might sell to a dealer for, multiply what you calculated by 30%. You'll be in the ball park. If you could sell to an end user buyer, the multiplication factor could probably be 50% to 60%.

As you compare your pieces to those at Replacements, be sure to check the length.

Best wishes,


Silver and Flatware
