He had had an earlier marriage in 1744 when he was fifteen. But the bride died after the marriage of a first child: a daughter. He needed to marry again. He had a further eight children. He never became king of France, rather it was his son who became the infamous Louis XVI who lost his head at the guillotine.
As Wikipedia says: On 10 January 1747, Louis was married by proxy at Dresden to Maria Josepha of Saxony, the 15-year-old younger daughter of Frederick Augustus II, Prince-Elector of Saxony and King of Poland and his wife, Archduchess Maria Josepha of Austria. A second marriage ceremony took place in person at Versailles on 9 February 1747.
This medal celebrates that second marriage ceremony in Versailles.
The second dish is an Austrian Franz Joseph 2 Florin. http://en.wikipedia.org/wiki/Franz_Joseph_I_of_Austria
The mark at the bottom of that dish is upside down but I believe it is the mark used on .800 silver by the Republic of Austria after 1922. The image is of a toucan, interestingly, I think, rather than the hoopoe bird. There should be two other marks next to the toucan: a 4 to the top right and I can see a W at the bottom left. The W tells us that it was assayed in Vienna.The makers mark looks like OO or is it OD?.
I haven't found a reference to OO. But if .....
