Post Your 'One Year Only' Coins (Not Commemoratives!)

Very nice!

Ah, the rare double-denomination "2/6 — 25¢". New Zealand had "One shilling — 10 cents" coins for a few years, but I think only Rhodesia had half-crowns with this transitional denomination. It's also a very early use of that effigy. Possibly the first?

Here's 2 more from Rhodesia 1964.

Federal Republic of Germany 10 pfennig 1949F (Stuttgart Mint):

The Bank Deutscher Länder (Bank of German States) was set up in what were then the Western Allies' occupation zones of Germany in 1948, and issued new coins to replace the wartime zinc Nazi issues. In 1950 the obverse legend on the coins was changed to Bundesrepublik Deutschland, to reflect that they were now the official currency of the German Federal Republic.

1 pfennig coins with the Bank Deutscher Länder legend were issued in 1948 and 1949, and 50 pfennig coins in 1949 and 1950, but 5 and 10 pfennig coins with this obverse only exist dated 1949.

Australia issued its first coins in 1910, bearing the portrait of King Edward VII.

He passed away later that year, so subsequent issues had the portrait of King George V:

Costa Rica has tended to outsource production of its coins to various foreign mints, resulting in occasional slight changes of design and metal content. For some reason the 1954 1- and 2-Colon coins were made of stainless steel rather than the usual cupro-nickel. Subsequent issues of both coins reverted to cupro-nickel, until 1982 when the coins were once again made of steel, but with a reduced size and modified design:

Very nice!

Only one way to find out...

Another WWII 1 year issue: Egypt 1 Qirsh 1944. Silver content was reduced to 50% from 83.3% previously used because of the increased cost of silver due to the war. This may have been the last silver coin Egypt produced for circulation.
