Overdate

1698/7 Half-Crown – William III Overdate - The Reverse shows crowned shields of England, Scotland, France and Ireland. In centre is the arms of Nassau. Legend is MAG BR FR ET HIB REX ET 1698, date divided and the 8 is struck over a 7.

1872/1 Gold Sovereign – Melbourne 2/1 Overdate - This was the first year that Melbourne Mint struck coins. There was a worry that the new dies may not arrive from London, so they modified the unused 1871 dies so as they would read 1872.
