Tiffany & Co. Sterling Silver Marks: How to Authenticate Any Piece
Tiffany & Co. has produced sterling silver flatware, hollowware, and jewelry since 1837, and their pieces appear regularly at estate sales, auctions, and consignment shops. A complete Tiffany Chrysanthemum dinner service for twelve can sell for $15,000–$40,000 at auction; individual serving pieces in rare patterns fetch $500–$3,000. Tiffany silver is also among the most misrepresented at sales — either genuine Tiffany sold as something else, or other makers' silver sold as Tiffany. This guide covers the marking system and authentication points in detail.
The Tiffany Silver Marking System
Genuine Tiffany & Co. sterling silver carries several marks on the piece: 'TIFFANY & CO.' in block capitals (or 'T. & Co.' on earlier pieces), 'STERLING' or '925,' and a pattern name or number. On flatware, these appear on the back of the handle. On hollowware, they appear on the base. The pattern designation is critical for value assessment: 'Chrysanthemum,' 'Audubon,' 'King William,' and 'Persian' are among the most valuable flatware patterns, with complete services commanding significant premiums. Maker's marks (letters indicating which workshop made the piece) also appear — 'M' indicates the period 1868–1902; 'c' indicates 1902–1907; 'c' in a rectangle indicates 1907–1947.
Dating Tiffany Silver by Workshop Letters
Tiffany's dating system uses letters that correspond to their makers: the letter 'M' without a cartouche indicates Edward C. Moore's workshop (1868–1891), representing some of the most desirable Tiffany silver. 'M' in a cartouche continues to 1902. After Moore, workshop letters changed — research the specific letter against published Tiffany silver references (Charles Carpenter's 'Tiffany Silver' is the standard). The letter appears alongside the Tiffany mark and sterling stamp. Earlier Tiffany silver (pre-1868) is marked 'TIFFANY, YOUNG & ELLIS' or 'TIFFANY & CO.' with older cartouche formats — these are extremely rare and valuable.
Common Misrepresentations and Fakes
The most frequent problem is not outright fake Tiffany but misidentification: other quality American silversmiths' work (Gorham, Reed & Barton, Whiting) sold as Tiffany. Compare the actual marks — if 'TIFFANY & CO.' is not present, it is not Tiffany regardless of quality or appearance. Outright fakes do exist, particularly in jewelry: look for incorrect font weight in 'TIFFANY & CO.' engraving, shallow stamp depth, and missing sterling marks. Tiffany never used silver plate — if you see 'EPNS' or 'Silverplate' alongside 'Tiffany,' it is not genuine Tiffany sterling. Tiffany presentation pieces (engraved with presentations) are genuine but sold at discounts due to personalization.
Condition Grading for Tiffany Flatware and Hollowware
Excellent (E): crisp pattern detail, no dents, light polishing only. Good (G): pattern detail slightly worn from polishing, no dents or repairs. Fair (F): heavy polishing wear, surface scratches, or repairs present. Pattern visibility is the primary value driver for flatware — heavily polished pieces where the relief pattern has worn to near-flat are worth 30–50% less than the same pieces with crisp detail. Monograms reduce value for most collectors (10–30% discount) but can occasionally add value on presentation pieces. Complete sets (12 of each piece type) command substantial premiums over partial sets.
On-Site Authentication Steps
Read the back of a flatware piece with a loupe — confirm 'TIFFANY & CO.,' 'STERLING,' and a pattern name or number are all present. Photograph the marks and compare against published references on your phone. Check the workshop letter against the date chart. Test silver content with a neodymium magnet — sterling is not magnetic. For hollowware, examine the base for all three marks (maker, sterling, pattern) and check for monogram removal (a disc soldered over the original engraving area indicates removal, reducing value). Bring a reference photo of the pattern name on your phone — confirming the actual pattern name can increase your negotiating position significantly.
