New Zealand twenty-cent coin pegged to the British pound, was changed to a decimal dollar at a rate of two dollars to a pound. Therefore, 20 cents was worth a tenth of a pound. The 20-cent coin replaced the florin coin which had been worth two shillings, or a tenth of a pound. Like the florin, the new 20-cent coin was made of cupronickel, 28.58 mm in diameter, 11.31 grams in weight, and had 100% edge milling.

The value of the guinea had fluctuated over the years from twenty to thirty shillings, and back down to twentyone shillings and sixpence by the start of George's reign. A Royal Proclamation of December 1717 fixed the value of the guinea at twenty one shillings. George II's two guinea pieces mark
