Swedish silver hallmarks
Swedish silver hallmarks have a trefoil cat’s-foot surround and can add an S for silver; three towers instead belong to the Danish system.
Distinctive marks and standards
The three crowns usually sit in a trefoil outline; a separate S can identify silver. Swedish date codes combine a letter and a cycle number, as in C10 for 1977.
What to check next
Three towers point instead to the Danish system. Read the town mark, responsibility mark and date code separately. A number following the letter is part of the Swedish year cycle, not a silver purity percentage.
