The quarter-guinea coin (20 pence) features the rose shield design from the last quarter-guineas ever issued, those under King George III.
The third-guinea piece (30 pence) features a royal crown, the only design used on the denomination since introduction.
The half-guinea (50 pence) features the garter design from the last circulating half-guineas ever issued, under King George III — the new shield of the Royal Arms.
The guinea (£1 and 5 pence) features the spade design from the last circulating guineas struck under King George III — a simplified shield with quarters.
The 5-guinea (£5) coin features the shield design from the very last 5-guinea pieces struck under King George III — a single ornate shield with quarters containing the arms of England and Scotland, France, Hanover and Ireland.
