The Thames foreshore wakes before London does. At 6 AM, when the river retreats on the low spring tide, the mudlarks arrive. Gumboots squelching. Eyes scanning. Hearts hoping.
I've been mudlarking the Thames for eight years. I don't do it for the money — most finds are worth pennies. I do it for the stories. Every piece of clay pipe, every worn button, every glint of trade token tells a tale of Londoners long gone. And sometimes, just sometimes, the river gives up something extraordinary.
The Thames has been London's rubbish bin for 2,000 years. Romans threw offerings to the river gods. Medieval apprentices dropped broken pottery from bridge windows. Victorian mudlarks — the original ones, poor children who scraped a living from the mud — hunted for anything sellable. Coal, rope, iron, bones.
Today, licensed mudlarks (you need a permit from the Port of London Authority) still hunt the same 50-foot strip of foreshore that revealed treasures to their Victorian counterparts. The river still gives. The trick is knowing where to look — and when.
I arrive at Bankside as the sun clears Tower Bridge. The mud is firm today — good walking. I scan the surface first, looking for the telltale shapes: blackened pottery, pale clay pipes, the glint of glass.
Hour One: Broken stems. Clay tobacco pipes snap easily, and the foreshore is carpeted with their ghosts. Most are Victorian — mass-produced, worth little. But a complete bowl with a maker's mark? That's a £20 find. I pocket three decent pieces, noting one has a visible stamp: "TD" — probably Thomas Dormer, Southwark, 1750s.
Hour Two: The mud gets interesting. I'm working a patch near an old ferry point, where passengers once crossed before bridges spanned the river. Trade tokens — small copper coins issued by businesses when official currency was scarce — turn up here. I find a 1660s coffee house token: "The Greate Coffee House at the Temple Barr." Worth perhaps £40, but priceless to me. I imagine the merchant who dropped it, cursing his luck, walking home lighter by a penny.
The Thames gives you ghosts. I once found a complete clay pipe, bowl unsmoked, stem pristine. A dockworker bought it, perhaps, on his way to a shift. Slipped from his pocket, never smoked his first bowl. Died maybe, or simply bought another. The river kept his pipe for 300 years. I keep it on my windowsill. I think of him sometimes, that unknown man, when I light my own.
Hour Three: Hunger and the cold bite. My fingers are numb despite neoprene gloves. But the tide is still retreating, exposing fresh mud. I'm searching by eye now, my brain pattern-matching for anything unusual. Then I see it — a flash of green in the grey.
A medieval strap mount. Bronze, still bright beneath the patina. 14th century perhaps, decorated with a fleur-de-lis pattern. Someone's belt fitting, lost in the crowds that thronged medieval London Bridge. I work the area carefully. Where there's one, there might be more.
Hour Four: The finds thin out. I'm working the "bone seam" now — a geological layer rich in animal remains from the butchers of Borough Market, centuries of discarded cow metatarsals and sheep jaws. Grim, but historically fascinating. I find a Georgian shoe buckle, silver-plated, still with its chape. Someone's Sunday best, lost on a drunken walk home in 1790.
Hour Five: The tide turns. I feel it before I see it — the water's energy changes, a subtle shift in sound. Time to climb the steps. I leave pieces behind, as mudlarks always do. Clay pipes arranged on wooden posts like offerings. A trail of history for others to find.
Most mudlarks hunt for years without finding gold. But it happens. In 2019, a mudlark named Jason Sandy found a gold Tudor ring inscribed "Be trew to thyne owne" — worth £10,000. In 2022, near Bermondsey, someone pulled a Roman gold aureus from the mud. First century AD. Unbelievable.
These aren't lottery wins. They're persistence prizes. The mudlarks who find gold are the ones who've spent a decade learning to read the foreshore, to recognize the subtle changes in clay colour that indicate undisturbed layers, to spot the corner of a coin peeking from the silt.
Want to try mudlarking? Here's what you need to know:
Back in my kitchen, I wash today's finds in warm water. The clay pipe stems turn from black to honey-coloured. The strap mount reveals its detail — a lion passant, the mark of English sterling quality control since the 14th century. This piece was quality, once. Owned by someone who cared about such things.
My fingers are stained black. My back aches. I've earned perhaps £60 in finds, if I sold them, which I won't.
But I held a 17th-century coffee token today. I found a belt fitting older than Shakespeare. I walked where thousands walked before me, and for a few hours, the river let me touch their world.
That's why we mudlark. Not for gold. For ghosts. For connection. For the bone-deep knowledge that London's history isn't in museums — it's in the mud, waiting for patient hands and open hearts.
The tide will turn again tomorrow.
I'll be there.
