Sweden 1920, 5 kronor. Gold, 2.02 g.



Sweden was on a gold standard (until 1931), but no gold coins had been minted since 1902. After World War 1, when banknotes could again be redeemed for gold, a single issue of the smallest gold coins was minted.

The brass, scalloped-edge coins issued by Paraguay in 1953 were obviously made for circulation, but there was never another issue.

The Netherlands, 2.5 Gulden, 1840.



Towards the end of the 1830's, it was decided by the Dutch government that the 3 Gulden piece did not really fit well in the monetary denominations of The Netherlands. As a result, in 1840 the 3 Gulden piece was demonetized, and the 2.5 Gulden piece ("Rijksdaalder") was struck. At the same time, the portrait of King Willem I was updated.
However, ever since the independence of Belgium (October 1830), more and more calls were heard in The Netherlands for a more liberal course and a matching change in the Constitution. Part of this change was to limit the power of the monarch. Willem I wasn't thrilled being no longer an absolute monarch but nevertheless signed the new Constitution under duress. However, when the Dutch parliament also refused to allow him to marry the catholic (gasp!) countess Henriëtte d'Oultremont de Wegimont, he promptly decided to abdicate on October 7th, 1840, in favor of his son, Willem II.
