Glasgow hallmark date letter “J”: which year?

Short answer

The letter J on a Glasgow hallmark can be any of these years, depending on its case and typeface: 1828–1829 (uppercase roman); 1854–1855 (uppercase gothic); 1880–1881 (uppercase sans-serif); 1906–1907 (uppercase cursive); 1932–1933 (lowercase roman); 1957–1958 (uppercase gothic).

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.
