The Gold Ryal, also known as the Rose Noble, was an English gold coin first issued in 1464, during the "first reign" of Edward IV (1461-1470). From the 1430s onwards, the price of gold had been rising, with the result that the gold noble, which had been in use since 1344, was worth more on the continent than in England. The nobles were exported en masse to the continent for profit, resulting in a shortage of the coins. F.S.Lewis
