The Royal Coin Cabinet is a museum dedicated to the history of money. The museum includes exhibitions of coins, banknotes (the first in the world was issued in 1661 by Stockholms Banco), treasure hoards and piggy banks. Particularly notable are the oldest Swedish coin, a copper plate coin dating from Queen Christina's reign in 1644 that is thought at 19.7 kg to be the heaviest in the world, some of the Lohe treasure found in 1937 on Gamla Stan, Weimar Republic inflation currency and some Nobel prize medals.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
