You've dug it up. It's round. It's definitely metal. But it's not quite a coin. The design is weird, the thickness is off, and the legends make no sense. Before you toss it in the "junk" pile, stop. You might be holding something far more interesting than you realise.
Welcome to the world of jettons and trade tokens - the overlooked treasures that tell stories official currency never could.
A jetton (from the French "jeter," meaning to throw) was a counting piece used for arithmetic before calculators existed. From the 13th to 17th centuries, merchants, clerks, and anyone doing accounts used jettons on a counting board - essentially an early abacus.
Picture a medieval merchant tallying up the day's sales. He'd lay out jettons on a cloth marked with columns for pounds, shillings, and pence, sliding them around to add and subtract. When the maths was done, the jettons went back in a pouch. Sometimes that pouch got lost in a field. Sometimes it fell in the mud outside a tavern. Sometimes the owner died of plague and never came back for it.
That's why you're finding them 500 years later.
Jettons can fool you into thinking they're coins. Here's how to tell the difference:
Now let's talk about trade tokens - a different beast entirely, but equally fascinating for detectorists.
In the 17th century, Britain had a small change crisis. The Royal Mint couldn't produce enough farthings and halfpennies for everyday trade. So merchants and traders started minting their own. From 1648 to 1672, over 12,000 different trade tokens circulated in England and Wales alone.
These weren't counterfeits - they were legitimate local currency. A baker in Canterbury might issue his own farthing tokens, redeemable for bread at his shop. A pub landlord in Tunbridge Wells might hand out tokens that were good for a pint at his establishment.
Then the government cracked down. Charles II banned private tokens in 1672 and started minting official copper coins. Traders with stockpiles of now-worthless tokens did what anyone would do - they threw them away or lost them.
Which is why we find them today.
Trade tokens often carry dates and locations, making them easier to identify than jettons:
Here's the thing about jettons and trade tokens: they're history from below. Royal coins tell you about kings and queens. Jettons tell you about the accountant who dropped one behind the counting house. Trade tokens tell you there was a blacksmith named Thomas in your village in 1668 who was important enough to mint his own money.
Find a 17th-century trade token in Kent, and you can often trace the exact shop it came from. The issuer's name, his trade, his town - it's all there on a disc the size of your thumbnail. That's not just a find. That's a person.
Jettons and tokens turn up wherever money changed hands:
The next time your detector pings on what looks like a thin, corroded "almost-coin," don't dismiss it. Clean it carefully. Photograph both sides. You might be holding a 600-year-old counting piece from Nuremberg, or the only surviving evidence of a tradesman who served your village four centuries ago.
That's not junk. That's history you can hold in your hand.
