A patent with a price tag

In the first half of 1722, the Duchess of Kendal, mistress of King George I, obtained a patent from the Earl of Sunderland to coin copper money for Ireland. It was, in the words of one account, a way of providing her with something to live on after the king's death. She did not intend to make coins herself. She sold the patent for £10,000 to William Wood, an English hardware maker and ironmaster who thought the venture would pay. In A History of Ireland in 100 Objects, Fintan O'Toole called the deal a classic episode of 18th-century sleaze, with sex and money nicely intertwined.

Wood's indenture from the king, dated June 16, 1722, let him produce up to 360 tons of halfpence and farthings for Ireland at 30 pence to the pound of copper, over fourteen years, for an annual fee of £800 to the Crown. The face value of the whole issue is usually given as £100,800; one modern collector guide gives £108,000.

The coins were generous. Hibernia halfpence were struck at sixty to the pound, heavier than the coppers then circulating in Ireland and twice the weight of Wood's lighter Rosa Americana pieces made for the American colonies at about the same time. The numismatist Philip Mossman calculated that, after production costs and the £10,000 paid to the duchess, Wood would have lost £4,871 over the life of the patent. Critics assumed the only way he could profit was by cheating on weight or quality.

Where the coins were struck is not settled. One account places the mint in Phoenix Street, Seven Dials, London, from January 1722. Documents quoted by the University of Notre Dame's coin collection point to London and Bristol and suggest striking did not begin until 1723.

William Wood, ironmaster

William Wood was born in Wolverhampton in 1671, the son of a silk weaver. He married Margaret Molineaux, daughter of a Willenhall ironmonger, in 1690, went into business with her father, and raised 14 children in a large Wolverhampton house called The Deanery. From 1714 he built a network of ironworks partnerships across the Midlands and Wales, and by 1723 he also ran the Falcon Iron Foundry in Southwark.

The Irish patent made him the most hated coiner in Ireland. Swift's first anonymous verse attack called him "Grazier, Tinker, Hard-Ware Man, Coiner, Counterfeiter, Founder and Esquire." Even his Dublin brothers-in-law, the ironmongers John and Daniel Molyneux, publicly disclaimed any connection with his coinage in 1723.

After losing the patent, Wood turned to a new process for making iron with mineral coal, invented by his son Francis and re-patented by Wood himself in 1728. He built large works on Frizington Moor near Whitehaven, but the company financing him received only about 10 tons of his iron. His plan for a million-pound Company of Ironmasters of Great Britain was under investigation by the Privy Council when he died on August 2, 1730. One historian has called that venture the Frizington Fraud.

Swift, the Drapier, and a kingdom that said no

Ireland's leaders objected from the start. In July 1722 William King, Anglican archbishop of Dublin, warned that the coinage would drain the kingdom of the little gold and silver left in it. The Irish revenue commissioners said there was no shortage of small change. In September 1723 the Irish Parliament sent the king an address protesting the coins and the "Clandestine and Unpresedented manner" in which Wood had obtained his patent. Ballads, pamphlets and even puppet shows mocked the scheme.

The campaign found its genius in Jonathan Swift, dean of St Patrick's Cathedral in Dublin. Writing as "M. B. Drapier," an ordinary Dublin cloth merchant, he published the first letter, addressed to the shopkeepers, tradesmen, farmers and common people of Ireland, in March 1724; by April he claimed more than 2,000 copies had sold in Dublin. The second letter followed on August 4, 1724, and on August 17 a group of Dublin bankers signed an agreement refusing to accept the coin. A third came on August 25.

London tried to calm things. Sir Isaac Newton, Master of the Mint, assayed sample coins and reported the copper was "of the same goodness and value" as England's own. Swift's side answered that Wood had chosen the coins Newton tested. Wood offered to cut the issue from £100,800 to £40,000 and to limit how many halfpence anyone had to accept in a single payment. None of it worked.

Swift's fourth letter, To the Whole People of Ireland, appeared around October 22, 1724, the day the new lord lieutenant, Lord Carteret, arrived in Dublin. It turned a dispute about copper into an argument about Ireland's constitutional standing: "You ARE, and OUGHT to be as FREE a People as your Brethren in England." Carteret called passages of it treasonable. The printer John Harding was arrested and a £300 reward was offered for the Drapier's identity. Nobody claimed it. Another anonymous paper by Swift urged the Dublin grand jury to stand up to the chief justice, and Harding was released.

In 1725 the government gave way and the patent was withdrawn. Wood received a pension of £3,000 a year for eight years, though he lived to collect it for only three. The blind harper Turlough O'Carolan marked the defeat with a tune called Squire Wood's Lamentation on the Refusal of his Halfpence.

Did Ireland's rejected coppers become American money?

Collectors of American colonial coins have long counted Wood's Hibernia pieces as part of their series, on the theory that the coppers Ireland refused were sent across the Atlantic. The record is genuinely contested.

The numismatic historian Brian Danforth argued that the coins were in fact accepted in coin-starved Ireland at first and stayed in use there until 1737, when regal Irish coppers replaced them. He traced their movement to America through trade and emigration: Irish emigrants in the famine of the late 1720s and again in the mid-1730s carried copper because it was compact and valuable, and once a new royal copper coinage for Ireland was announced in 1736, Wood's coins were shipped to the colonies in bulk, especially to New York and the other Middle Colonies that traded most with Ireland.

Philip Mossman reached the opposite conclusion, writing that "there is no evidence of any substantial colonial circulation for these coppers," and suggesting some reached the United States only in the early 1800s alongside English trade tokens. The Notre Dame collection's summary sides with him and notes that very few Wood's Hibernias have been found in Ireland either.

Some certainly made the crossing. On July 20, 2012, an archaeological dig on Huguenot Street in New Paltz, New York, turned up a corroded 1723 Hibernia halfpenny in the ground between two of the street's historic stone houses.

Identifying a 1723 halfpenny

The 1723 halfpenny shows George I's laureate bust facing right with the legend GEORGIUS DEI GRATIA REX. On the reverse, Hibernia, the personification of Ireland, sits holding a palm branch in her right hand and leaning on a harp behind her, with HIBERNIA and the date. Most 1722 coins show her playing a harp placed to the left instead; all 1723 and 1724 coins use the palm-branch design. The coin is about the size of a modern U.S. quarter.

The striking thing to specialists is how many dies were used. Hibernia's figure was punched into each die with a blank harp, and the engravers cut the strings by hand, so the count of strings varies. Different letter punches, stops, star ornaments and die states multiply the possibilities. Sydney Martin's studies, published in the 1990s and in his 2007 book on the Hibernia coinage, assign each coin a number such as Martin 4.34-Gb.3; one estimate put the total number of halfpenny varieties at 200 to 400. Rare die marriages can sell for many times the price of a common one, even in worn condition: a Very Fine 1723 halfpenny of an unlisted variety, with a small star before the date, brought $12,925 in 2013.

The year 1723 is the commonly encountered Hibernia halfpenny, but most survivors are worn. Gem examples with original mint color are scarce. In 2014 one grading service had awarded Gem status to just six 1723 halfpence in all color grades. Among the finest pedigreed pieces is an MS65 Brown coin that belonged to Colonel E.H.R. Green and then to Eric P. Newman, whose records show he paid $3.00 for it; it was sold from his collection in New York in May 2014.

Weights vary. A collectors' catalog lists the type at about 7 grams and 27.5 millimeters in copper, while individual 1723 coins have been recorded at 129.3 grains and at 109 grains.

A small coin with a long reach

The affair of Wood's halfpence is remembered in Ireland less as a coinage than as a political awakening. The National Museum of Ireland's halfpenny was chosen as one of the objects in A History of Ireland in 100 Objects, where O'Toole argued that the Drapier's idea of Ireland as a free and equal kingdom had an ambiguous life in Protestant Ireland but "a more potent one in America." Swift's admirers called him the Hibernian Patriot, and the complete Drapier's Letters were first collected and published in Dublin in 1735.

For collectors, the 1723 halfpenny remains one of the most available ways to own a coin tied to colonial America, and one of the deepest variety series in early copper. Ordinary circulated pieces trade for modest sums, while gems and rare die marriages draw specialist competition.

A realized auction price is what a buyer actually paid on the date shown, including the buyer's premium where the sale reported it. It is the strongest kind of reference price, and it is a record of one sale of one object on one day, not a promise of what the next example will bring.

By reference price, 1723 Wood's Hibernia Halfpenny is number 100 of 100 in the coins entries of the FLOAT 100. 96 of those 100 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (54 here) is editorial: how much an object defines its field, not price alone.
