Monarchs Come Together at Recent Sales

Coins depicting King William III and Queen Mary II, the only joint monarch portraits in British coinage, continue to command interest and strong prices at auction.

In late seventeenth-century Britain, not just one, but two portraits of royals were featured on circulating coinage: King William III and Queen Mary. The duo jointly ruled as a double monarchy of England, Scotland, and Ireland after the deposition of England’s last Catholic king, James, during the Glorious Revolution of 1688. Protestant Queen Mary II, who was the niece of King Charles II, and her husband, Dutch royal William III of England, were then given the crown from 1689 until her death from smallpox in 1694. William continued to rule until his death from pneumonia in 1702. Throughout their reign, new issues were minted that visually paired the two monarchs together.

Fast forward over 300 years, and these rare pieces have held prominence at recent auctions and are now prized collectors’ items. They remain as the first and only examples of a dual-monarchy portrait on a British coin.
A recent 1691 example caught collectors’ attention with an ultra-rare gold 5 guinea coin (lot 125) at the March 18 Jewellery Roseberys London sale, which sold for £11,808 to a UK buyer. “This rare coin is a relic of the only time in history when a husband and wife ruled together as equal monarchs. The result reflects its immense rarity and historical importance,” says Catrin Jones GIA GG MJVA, head of jewellery at Roseberys London.

This 5-guinea issue was of the highest circulating denomination in the late 17th century and was produced in limited numbers. “Only the wealthiest members of society would have handled such a coin,” explains Jones. “The value of the gold will have led many to be melted over the years, increasing the rarity.”

On the obverse of the toothed bordered coin are the profiles of William III and Mary II, and framing the subjects are the Latin legend “GVLIELMVS. ET. MARIA. DEI GRATIA” (William and Mary by the grace of god) and pellet stops. The reverse shows a crowned quartered shield of arms with an escutcheon of the Lion of Nassau that is framed by Latin legends reading, “MAG. BR. FR. ET. HIB REX. ET” (King and Queen of Great Britain, France, and Ireland) and “DECVS ET TVTAMEN ANNO REGNI TERTIO” (An ornament and a safeguard, in the third year of the reign).
