Making sense of Tiffany Studios’ desk set numbering

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Having known Phil Chasen my entire life, I jumped at the chance to contribute when asked to be a guest on his blog. Hopefully you will check back in the future for additional Tiffany Studios articles. –Jamie

stamp 10stamp 6Much is made of signatures (typically for good reason!) in the world of Tiffany Studios desk set pieces, but with light research and deduction, it can be fairly easy to make sense of what seems to be anomalous. Most Tiffany desk set pieces bear a three or four-digit registration number along with the “TIFFANY STUDIOS” or “TIFFANY STUDIOS NEW YORK” stamp, while others are simply marked with the studio name. Three and four-digit numbers correspond to individual items. For instance “801” refers to Etched Metal & Glass (Grapevine or Pine Needle) stamp boxes. What confuses some people are the pieces with two-digit numbers. Apparently the two-digit numbers were used for assembly, as many of Tiffany’s desk items were complicated and constructed of multiple pieces. The separate pieces typically bear an assembly number somewhere, usually hidden once constructed.

Above is a Tiffany Studios stamp box in the classic Grapevine pattern, with registration number 801. While signatures (or lack thereof) are not the sole defining characteristic of Tiffany desk set pieces, a basic understanding of them can easily help a collector choose pieces that are correct but seem anomalous or, on the other hand, avoid pieces that do not coincide with any published information.
