The finest error in my Swedish error collection is this 2 Ore 1964 with a struck in tool. How could such a coin came out from the Mint? The story behind this coin is quite interesting. The tool was used by the Mint employees to remove coins that were jammed in the die and the collar. A Mint employee tried to loosen a particular coin and the dies struck the blank with the tool, bonding it with the coin. This is a unique and spectacular mint error. I found this item at a coin-dealer in Stockholm. He told me that it came from a former Mint Director.
