The seal of Karl, discovered in the early 1990s, is dated to the end of the 12th century and thus the oldest preserved personal object in Swedish history. Personal seals were normally broken to pieces at the death of the owner in order to prevent later abuse, and the intact seal of Karl is therefore unique.[4] The Swedish Museum of National Antiquities bought it in 2001 for SEK 800,000.[5]
