1 Öre - Gustaf VI Adolf Aluminium Pattern

Sweden's transition away from bronze coinage for the lowest denominations was long in coming, and by the mid-1960s the Riksbank was actively testing aluminium as a cheaper alternative. These 1967 patterns were part of that evaluation — lightweight, corrosion-resistant, and cheap to produce in bulk. The reform ultimately went a different direction: the 1972 monetary decimalization wiped out the öre's smallest subdivisions entirely, rendering the whole exercise moot before it reached circulation.
