Penny of William I

The Penny of William I is the standard silver coin of England under William the Conqueror, first Norman king of the English. The example shown here carries a profile portrait of the king on the obverse and a cross with decorative elements on the reverse, a design scheme dated to around 1075. It is a thin, broad hammered coin struck on a small flan of good silver, continuing the fabric of the late Anglo-Saxon penny.

Throughout William's reign the penny was effectively the only denomination in circulation, so this coin did the work of an entire currency. Collectors value it as the money of the Norman Conquest itself, and the different portrait styles and cross-based reverses are grouped by numismatists into a sequence of named types issued across the reign.

William I took the English throne after his victory at Hastings in 1066 and ruled until 1087. Rather than sweep away the existing money, the Normans inherited and continued the sophisticated late Anglo-Saxon coinage system, keeping the silver penny as the sole regular denomination and maintaining the practice of periodically changing the coin's design across the reign.

Pennies were struck at many mints across England by named moneyers, whose names and mint towns appear in the reverse legend, a system of accountability carried over from before the Conquest. The reverse of this circa-1075 issue is built around a cross with decorative elements, a long-standing motif on English pennies that carried both religious meaning and the practical function of guiding the coin's division into halves and quarters. The penny of William I set the pattern that continued under his son William II and successors.

Look for a thin, broad silver coin roughly 18-20 mm across and light in the hand, typically weighing on the order of about 1.3-1.5 grams, struck by hand so the flan is often slightly irregular or off-center. The obverse shows a profile portrait of William I; the reverse of this type is a cross with decorative elements. Both sides carry Latin legends around the edge.

Read the legends where they survive. The obverse names the king (forms of PILLELM or similar for William), while the reverse gives the moneyer's name and the mint town, so a partly legible reverse can tell you where and by whom the coin was struck. Because the coins were hammered, expect weak areas, uneven borders, and letters that run off the flan; this is normal for the type and not a sign of a problem.

Pennies of William I are genuinely medieval and desirable, and they command meaningful prices even in modest grade, with well-centered, clearly legible examples worth substantially more than worn or clipped pieces. Value is driven strongly by how much of the portrait and legend survives, the completeness of the flan, and the specific type and mint, as some mints and moneyers are much scarcer than others.

Because each coin is individually struck and struck-off flans, cracks, and partial legends are common, prices vary widely and are best judged against recent comparable sales rather than a single figure. Provenance and, for detector finds, lawful reporting under treasure and portable-antiquities rules can also affect both legality and value. Treat any estimate as approximate and confirm with a specialist reference or dealer.
