Irlandes d'Argent Público Deposited
Ruding (i. 278) states that at the Parliament at Drogheda in 1460 it was enacted that " a proper coin separate from the coin of England, was with more convenience agreed to be had in Ireland," and among the proposed coins was one " of half quarter of an ounce troy weight, on which shall be imprinted on one side a lion, and on the other side a crown, called an Irlandes d'Argent, to pass for the value of one penny sterling."
