Bonnet-piece, a gold coin of James V. of Scotland, so called on account of the king's head being decorated with a bonnet instead of a crown, as was usual. James V. was the first Scottish sovereign to place dates on his money, and to diminish the size of the gold coins by increasing their thickness. His bonnet-pieces were struck of native gold, and are now much prized by collectors. See Edward Burns' Coinage of Scotland (1888).
