12 Shillings - Charles I 3rd Coinage, 4th Issue

Charles I's Scottish coinage was administered through a crown-controlled mint in Edinburgh, and the 4th Issue of the 3rd Coinage falls squarely within the period when his relations with Scotland were collapsing. The Bishops' Wars of 1639–1640 — Scotland's armed resistance to Charles's imposition of Anglican liturgy — were already underway when these pieces were being struck, making this a coin produced by a king actively at war with the very country whose money he was issuing.

The 12 shilling denomination was peculiar to Scotland's independent monetary system, which ran on a pound valued at one-twelfth of the English pound sterling.
