Birmingham hallmark date letter “X”: which year?
Short answer
The letter X on a Birmingham hallmark can be any of these years, depending on its case and typeface: 1795–1796 (uppercase roman); 1821–1822 (lowercase roman); 1846–1847 (uppercase gothic); 1872–1873 (uppercase roman); 1897–1898 (lowercase gothic); 1922–1923 (lowercase roman); 1947–1948 (uppercase roman); 1972–1973 (uppercase cursive); 1997 (uppercase roman, unified cycle); 2022 (lowercase roman, unified cycle).
Before 1975 the letter changes in July, so most letters span two calendar years. Compare the case and typeface with the table; the letter alone does not settle it.
