London hallmark date letter “L”: which year?

Short answer

The letter L on a London hallmark can be any of these years, depending on its case and typeface: 1786–1787 (lowercase roman); 1806–1807 (uppercase roman); 1826–1827 (lowercase roman); 1846–1847 (uppercase gothic); 1866–1867 (lowercase gothic); 1886–1887 (uppercase roman); 1906–1907 (lowercase roman); 1926–1927 (lowercase gothic); 1946–1947 (uppercase sans-serif); 1966–1967 (lowercase cursive); 1985 (uppercase roman, unified cycle); 2010 (lowercase roman, unified cycle).

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