Edinburgh hallmark date letter “X”: which year?

The letter X on a Edinburgh hallmark can be any of these years, depending on its case and typeface: 1829–1830 (lowercase roman); 1854–1855 (uppercase gothic); 1879–1880 (uppercase sans-serif); 1903–1904 (lowercase gothic); 1928–1929 (uppercase roman); 1953–1954 (uppercase cursive); 1997 (uppercase roman, unified cycle); 2022 (lowercase roman, unified cycle).

Before 1975 the letter changes in September, so most letters span two calendar years. Compare the case and typeface with the table; the letter alone does not settle it.
