If there is ever a question about the content of a piece of jewelry, the manufacturer can be traced using the hallmark stamped on the piece....US law requires a maker's mark in the form of a hallmark or registered trademark in addition to the quality mark if the goods are quality marked.One concave line represented 140/1000 fineness, a straight one 150 and a convex one 160.For example, a Diana head within a frame made in the shape of a 5-petal flower represented 5x160 = 800 thousands fineness, a local silver standard commonly used in eating forks and spoons.Without access to the Tiffany archives, they have no real meaning.1851 ~ 1 1856 ~ 301 1860 ~ 1,001 1865 ~ 1,551 1870 ~ 2,251 1875 ~ 3,801 1876 ~ 4,545 1877 ~ 4,620 1878 ~ 5,050 1879 ~ 5,370 1880 ~ 5,910 1881 ~ 6,260 1882 ~ 6,760 1883 ~ 7,300 1884 ~ 7,840 1885 ~ 8,340 1886 ~ 8,800 1887 ~ 9,260 1888 ~ 9,660 1889 ~ 10,120 1890 ~ 10,400 1891 ~ 10,820 1892 ~ 11,140 1893 ~ 11,520 1894 ~ 11,940 1895 ~ 12,220 1896 ~ 12,600 1897 ~ 13,040 1898 ~ 13,510 1899 ~ 13,900 1900 ~ 14,250 1901 ~ 14,650 1902 ~ 15,145 1903 ~ 15,550 1904 ~ 15,943 1905 ~ 16,356 1906 ~ 16,555 1907 ~ 16,849 1908 ~ 17,103 1909 ~ 17,272 1910 ~ 17,596 1911 ~ 17,880 1912 ~ 18,190 1913 ~ 18,395 1914 ~ 18,601 1915 ~ 18,808 1916 ~ 18,996 1917 ~ 19,193 1918 ~ 19,460 1919 ~ 19,521 1920 ~ 19,683 1921 ~ 19,831 1922 ~ 20,021 1923 ~ 20,160 1924 ~ 20,296 1925 ~ 20,470 1926 ~ 20,664 1927 ~ 20,845 1928 ~ 21,177 1929 ~ 21,352 1930 ~ 21,470 1931 ~ 21,724 1932 ~ 21,855 1933 ~ 21,950 1934 ~ 21,987 1935 ~ 22,100 1936 ~ 22,280 1937 ~ 22,360 1938 ~ 22,575 1939 ~ 22,650 1940 ~ 22,850 1941 ~ 22,950 1942 ~ 23,140 1944 ~ 23,164 1945 ~ 23,177 1946 ~ 23,204 1947 ~ 23,238 1948 ~ 23,250 1949 ~ 23,274 1950 ~ 23,310 The Tiffany dynasty was founded in 1837 at 259 Broadway in New York City by Charles Louis Tiffany and partner John B. It began not as a jewelry & silver emporium, but as a purveyor of stationery and fancy goods under the name Tiffany & Young. Ellis joined the firm and the name changed to Tiffany, Young & Ellis.

While American manufacturers did not apply assay marks, city marks or date marks, they did apply a maker's mark. The old hallmarks were as unique as today's logos, and disputes often arose when one company copied another's stamp.Since these could vary considerably in purity, from around .750 millesimal fineness to around .900, silver known as "coin silver" varies in purity.Silver at that time was sometimes marked "COIN" or "PURE COIN", but can also be without a standard mark altogether.(about 1870) and Tiffany began the production of its own silverware, it became the tradition to mark each piece with the initial of the Artistic Director or President of the firm. Tiffany & Co's use of Pattern numbers allows us to date when a design was first put into production, as many popular designs were produced for many years, they only provide a guideline.

Using them in conjunction with the director's initial mark does often give a fairly accurate circa date.

There are many variations in the maker's marks used by Tiffany & Co., the below is only intended to give a basic guideline to the holloware markings.
