[A]s Felix Martin points out in his book, Money: The Unauthorised Biography, that most of our monetary history hasn't survived in a form that could grace a museum.

In fact, in 1834, the British government decided to destroy 600 years of precious monetary artefacts. It was a decision that was to have unfortunate consequences in more ways than one.

The artefacts in question were humble sticks of willow, about eight inches (20cm) long, called Exchequer tallies. The willow was harvested along the banks of the Thames, not far from the Palace ofWestminster in central London.

Tallies were a way of recording debts with a system that was sublimely simple and effective.

The stick would contain a record of the debt, for example: "£9 4s 4d from Fulk Basset for the farm of Wycombe". Fulk Basset was a Bishop of London in the 13th Century. He owed his debtto King Henry III.

Now comes the elegant part.

The stick would be split in half, down its length from one end to the other. The debtor would retain half, called the "foil". The creditor would retain the other half, called the"stock" - even today, British bankers use the word "stocks" to refer to debts of the British government.

Because willow has a natural and distinctive grain, the two halves would match only each other.

Of course, the Treasury could simply have kept a record of these transactions in a ledger somewhere. But the tally stick system enabled something radical to occur.

If you had a tally stock showing that Bishop Basset owed you £5, then unless you worried that he wasn't good for the money, the tally stock itself was worth close to £5 in its own right. Ifyou wanted to buy something, you might well find that the seller would be pleased to accept the tally stock as a safe and convenient form of payment.

So the tally sticks themselves became a kind of money, a particular sort of debt that could be traded freely, circulating from person to person until it utterly separated from Bishop Basset and afarm in Wycombe.

Notched pieces of wood or bone were used by many ancient peoples to record numbers. The most common type of these "tally sticks" was made of wood. Tally sticks served as records or receipts forfinancial transactions such as the payment of taxes, debts and fines. From the 12th century onward tally sticks were officially employed by the Exchequer of England to collect the King's taxes. Localsheriffs were given the task of actually collecting the taxes. The depth and series of notches on these sticks represented the value of the transaction. In recording a debt, a wooden stick was oftensplit horizontally into two parts: the lender receiving one part, the stock; and the debtor, the other part, the foil. This box contains sticks that date from the year 1296 and were found in theChapel of the Pyx, Westminster Abbey in 1808. England abolished the use of tally sticks in 1826. The accumulation of tally sticks in the Office of the Exchequer were burned in 1834 resulting in afire that destroyed the Parliament Building.
