1000 Krónur Law of 1961

Pick 52 was issued under the Law of 1961 but didn't enter circulation until the 1980s — a gap that reflects how slowly Seðlabanki Íslands refreshed its higher denominations during that period. The 1000 krónur was a substantial sum in Iceland at the time, and the denomination circulated alongside a monetary system that would be overhauled entirely in 1981, when Iceland redenominated at 100:1, introducing the new króna. That reform makes the dating of individual notes within the 1981–1986 window significant: earlier printings predate the redenomination, later ones postdate it.

Bradbury Wilkinson and De La Rue both appear in the printer record, suggesting production shifted between the two firms across the issue's lifespan — not unusual for a long-running series.
