A thin flash of silver in the clod can make any detectorist's pulse jump. But before you decide whether it is medieval, Tudor, Georgian or Victorian, the first question is simple: hammered or milled?
Hammered silver coins were struck by hand between dies. In England, that tradition runs through the medieval period and into the early modern age, with the final hammered issues ending in the later seventeenth century. Milled coins, made with machinery, gradually replaced them and usually look more regular, more circular and more standardised.
In the field, though, mud is a great leveller. A clipped hammered penny, a bent Elizabethan sixpence, a worn William III shilling and a small Victorian silver threepence can all arrive as pale discs with very little obvious detail. The trick is to slow down and read the object in layers.
Hammered coins are often slightly irregular. Their flans can be oval, ragged, off-centre or clipped around the edge. They may feel thin and light, especially cut halfpennies and farthings. The design may run off one side because the blank was not perfectly aligned when struck.
Milled silver usually has a more even circle and a more deliberate edge. Later pieces may show reeding, lettering or a cleaner rim. Even when badly worn, a milled coin often feels more engineered in the fingers. Small silver threepences, sixpences and shillings can still be thin, but the roundness is normally a clue.
Do not rub silver clean in the field. A gentle rinse with water later is far safer than grinding soil across the surface. Even a tiny visible fragment can help: part of a cross, a shield, a bust, a rose, a crown, or a few letters from the legend.
Hammered coins often carry long Latin inscriptions around a central design. Medieval pennies may show a facing bust on one side and a long cross on the other. Tudor and Stuart hammered silver can show distinctive portraits, shields and mintmarks. Milled coins are more likely to have a neater bust, clearer date placement and a more balanced layout.
If you can photograph both sides beside a scale, you give yourself a much better chance of identification later. Diameter and weight are extremely useful, especially for hammered silver where a few millimetres can separate a penny from a halfgroat or groat fragment.
A single silver coin is exciting, but the surrounding finds tell the bigger story. Medieval buckles, lead tokens, pottery and strap fittings may support a hammered identification. Georgian buttons, shoe buckles, watch keys and worn copper coins may point towards later milled silver losses. Mixed evidence can reveal centuries of movement across the same line of travel.
Record the findspot carefully. Silver coins, especially older examples, can be important evidence for trade, settlement and routeways. If the coin may qualify as Treasure, or if you have a group of associated precious-metal objects, stop, protect the context and report it through the proper channels. The Portable Antiquities Scheme can also help identify and record single finds that add to the national picture.
The best detectorists are not just treasure hunters; they are readers of clues. A silver signal is a thrill, but the real reward is working out who lost it, when they lost it, and why that particular patch of soil mattered.
