Scottish gold coin, minted in 1540. The name is derived from the obverse portraying King James V in a large, flat bonnet. The following extract from Tales of a Grand-father gives Sir Walter Scott's account of the coin which is also known as the Crawford dessert.

"James V. ordered the mineral wealth of Scotland to be inquired into. He obtained miners from Germany, who extracted both silver and gold from the mines of Leadhills, in the upper part of Clydes-dale. The gold was of fine quality, and found in quantity sufficient to supply metal for a very elegant gold coin, which, bearing on one side the head of James V., wearing a bonnet, has been thence called a bonnet-piece.

It is said that upon one occasion the king invited the ambassadors of Spain, France, and other foreign countries, to hunt with him in Crawford Moor, the district in which lie the mines I have just mentioned. They dined in the castle of Crawford, a rude old fortress. The king made some apology for the dinner, which was composed of the game they had killed during the hunting and hawking of the day, but he assured his guests that the dessert would make them some amends, as he had given directions that it should consist of the finest fruits which the country afforded. The foreigners looked at each other in surprise, on hearing the king talk of fruits being produced amidst the black moors and barren mountains around them. But the dessert made its appearance in the shape of a number of covered saucers, one of which was placed before each guest, and being examined was found full of gold bonnet-pieces, which they were desired to accept as the fruit produced by the mountains of Crawford Moor. This new sort of dessert was no doubt as acceptable as the most delicate fruits of a southern climate. The mines of the country are now wrought only for lead, of which they produce still a very large quantity."
