This shows a letter or a letter and number that relates to the year in which the article was hallmarked.

When examining the year mark, you must also compare the comtrol mark to establish which year mark series the item falls into because the year marks are partly the same. One crown is 1810 onwards, three crowns is 1759-1809. If instead of a crown there is the Oltermanni line control mark (see the photograph on the Control Marks page), you must also take the place mark into consideration.

The current series of year marks began in 1810 with the letter A. Whenever the alphabet was complete (regardless of date series), it would begin again with the addition of a number (e.g. A2, A3). The letters J, Å, Ä and Ö were excluded. Be aware that often the letter and number was made using separate stamps. As such, the number may sometimes appear before the letter.

Be particular careful of the fineness mark '13' (1853-1886) as this can sometimes be confused with the year mark 'I3'.
