William Wood, owner of several copper and tin mines, hoped to make a profit producing coins for use in Ireland and America. During the first half of 1722 the king's mistress, the Duchess of Kendal, obtained a patent from the Earl of Sunderland for coining copper money for Ireland. Wood thought this would be a profitable enterprise so he purchased the royal patent from the duchess for £10,000. In his indenture from George I dated June 16, 1722 Wood was authorized to produce up to 360 tons of halfpence and farthings for Ireland at 30 pence to the pound over a period of fourteen years for an annual fee of £800 paid to the king. These Hibernia coins were heavier and thus intrinsically more valuable than the coppers then circulating in Ireland. They were certainly less profitable for Wood to mint than his lighter weight Rosa Americana issues. (Hibernia's weighed sixty halfpence to the pound as compared to 120 Rosa Americana halfpence to the pound!). When including the costs of production and the £10,000 fee paid to the Duchess of Kendal, Mossman has calculated Wood would have lost £4,871 over the fourteen years of the patent. Thus from Wood's standpoint the Hibernia coin specifications were too generous based on the cost of production.
