In 1968, the 2-kronor switched to cupronickel and the 1-krona switched to cupronickel-clad copper (it was replaced entirely by cupronickel in 1982). Nonetheless, all previous mintages of the 1-krona (since 1875) and 2-kronor (since 1876) were still legal tender until 2017, though 2-kronor coins were extremely rarely seen in circulation as they have not been issued since 1971. The 2-kronor coins contained 40% silver until 1966, which meant they had been for several years worth much more than face value, so most have been bought and melted down by arbitrageurs, and the rest are kept by collectors.
