Over four days in Paris I picked up three coins from the street - a one eurocent, a two eurocents and a five eurocents. None filled in any gaps in my collection!
It's been a great game, MachinMachinMan! I have just realised that, while there is a coin posted for 1717 to represent the United Kingdom, there are no coins from the Kingdom of Scotland or the Kingdom of England, which had separate currencies before the Act of Union in 1707...
So here is my rather unattractive, twice holed, 1701 William III silver threepence to represent the Kingdom of England!
This 1703 sixpence and 1709 shilling show a change in the four shields on the reverse. From 1603 to 1707, the kingdoms of Scotland and England were separately governed even though they shared a monarch. After the Act of Union the countries were united, so the English and Scottish arms are conjoined. Both coins also have the arms of Ireland, and... France! Historically the English monarch had a claim to the kingdom of France, although the last English possession on the French mainland had been lost in the mid-16th century! English coins continued to proclaim the monarch as king / queen of France until the French revolution!
