King Consorts shouldn't be included, as they were not ruling monarchs in Scotland.
Both of these men did rule in Scotland. Francis, on account of his age, did not exercise personal power in Scotland. Instead, Queen Mary of Guise ruled as regent on behalf of her daughter and son-in-law. He is named on all of the coins issued during his marriage to Mary and is depicted on one of them. His name is placed before Mary's name in the legends, thereby symbolising that he was the senior monarch.
Here are some examples: 1 Ducat - Francis and Mary (2nd Period) - Scotland – Numista
½ Testoon - Francis and Mary (2nd Period, Type II) - Scotland – Numista
Henry Darnley controversially ruled as king alongside Mary. This controversy plays out on the coinage itself, with Henry initially being named first on Mary's coins: 1 Ryal - Mary and Henry Darnley (4th Period, Type I) - Scotland – Numista This was soon replaced by a coin that placed his name second: 1 Ryal - Mary and Henry Darnley (4th Period, Type II) - Scotland – Numista There is also a 1566 dated palm tree ryal that names Henry first, but the two surviving specimens are of questionable authenticity.
The catalogue guidelines state: ‘Add junior rulers or consorts of senior rulers, only if they are depicted on the coin.’ Therefore, shouldn't both men be listed as Scottish ruling authorities? Their inclusion would also provide a convenient way of searching for the coins of Mary that feature them.
