Picture a medieval traveller, exhausted after weeks of walking, finally reaching Canterbury Cathedral. They've journeyed from London, Dover, or perhaps as far as York. They've prayed at the shrine of Thomas Becket. And before leaving, they do what tourists have done for centuries - they buy a souvenir.
That souvenir might now be lying in a field you're about to detect. Here's how to find one.
Pilgrim badges were small metal tokens sold at religious shrines throughout medieval Europe. Made from cheap lead-tin alloy, they were affordable souvenirs that even poor pilgrims could buy. Pinned to hats or cloaks, they proved you'd completed your pilgrimage. They were Instagram posts made of pewter.
Between the 12th and 16th centuries, millions were produced. England's major shrines - Canterbury, Walsingham, Westminster, Durham - each had their own distinctive designs. Some pilgrims collected dozens, wearing them like medieval travel patches.
Then Henry VIII dissolved the monasteries. The shrines were destroyed. The pilgrimages ended. And countless badges were lost, discarded, or buried - waiting for us to find them.
For Kent detectorists, Canterbury badges are the holy grail. After Thomas Becket was murdered in the cathedral in 1170, Canterbury became England's premier pilgrimage destination. Geoffrey Chaucer's pilgrims were just a fraction of the millions who made the journey.
Canterbury badges typically show:
These ampullae are the most commonly found Canterbury souvenirs. Shaped like small bottles, about an inch tall, they were filled with "Canterbury Water" - water supposedly tinged with the saint's miraculous blood. Pilgrims believed it could cure illness, protect from danger, and guarantee salvation.
Canterbury wasn't alone. Badges from other shrines turn up regularly:
Continental badges also appear in British soil. English pilgrims travelled to Rome, Santiago de Compostela, and dozens of European shrines. Finding a scallop shell badge from Compostela in a Sussex field isn't impossible - it tells the story of a medieval traveller who made an epic journey across Europe.
Here's the challenge: pilgrim badges are small, fragile, and made of non-ferrous metal that can look like junk. Most are between 20-50mm, thin as a coin, and often broken.
Your detector will read them similarly to buttons or small buckles - typically in the mid-range for non-ferrous signals. The real identification happens after you've dug the target.
Look for:
Pilgrim badges turn up on medieval routes and stopping points:
The Thames foreshore is also productive for mudlarkers. Pilgrims crossing London Bridge often lost badges to the river below. But for field detectorists, focus on the land routes between major shrines.
Not all pilgrim badges were pious. Medieval England had a thriving trade in what scholars politely call "secular badges" - bawdy, obscene, and sometimes bizarre tokens that mocked religious souvenirs. Flying phalluses, walking vulvas, and other anatomical impossibilities were sold alongside saints' images.
These weren't blasphemous - medieval humour was earthier than ours. They were jokes, lucky charms, or fertility tokens. Finding one is rarer than finding a religious badge, but they do turn up. Don't assume that strange shape is a manufacturing defect.
Most pilgrim badges aren't valuable in monetary terms. A common ampulla might sell for £30-100. But rare examples from unusual shrines, or exceptionally preserved pieces, can reach thousands. In 2019, a Canterbury badge showing Becket's murder sold at auction for over £4,000.
The real value is historical. Each badge represents one person's medieval journey - their faith, their hopes, their footsteps along ancient roads. You're holding something that was once pinned to a traveller's cloak, carried through forests and across rivers, touched in prayer.
That story is priceless.
Pilgrim badges should be recorded with the Portable Antiquities Scheme. They're not treasure (unless gold or silver), but they contribute to our understanding of medieval pilgrimage. The PAS database now contains thousands of badge records, mapping routes and revealing patterns that historians never knew.
Your find could be the missing piece in that puzzle.
So next time you're hunting a field near an ancient church, a medieval crossing, or an old road, think about who walked there before you. Millions of pilgrims, seeking miracles, carrying cheap metal souvenirs that proved they'd made the journey. Some of those souvenirs are still waiting.
Happy hunting.
