Why a wooden tally stick was split in two
A notch recorded an amount; the split made two matching records. Surviving museum objects show how the system worked and what a lone half cannot prove.
A wooden stick can hold an account, but the clever part of a split tally is that neither party has to keep the only copy. Notches mark the amount; splitting the stick makes two related records that can later be brought together.
One record becomes two
The Bank of England’s museum timeline describes a hazelwood tally recording one of the Bank’s first loans to the government in 1694. Notches represented the total debt. A lengthwise split then gave each party a record.
The order matters to understanding the idea: this is not two unrelated sticks with approximately similar marks. The shared origin is the point. Imagine recording an agreement and then dividing its physical record between the people involved.
Why the split mattered
The Science Museum Group’s account explains that matching halves, including the wood’s individual features and its split, made forgery harder. The check involved the object itself, not just reading a number.
That gives a useful way to distinguish two jobs the tally performed. The marks recorded information; the fit helped connect the two records. One job did not replace the other. A stick without readable marks would pose different questions from a marked piece whose matching half had been lost.
Stock and foil
London Museum’s 1695 example describes unequal halves: a longer stock given to the payer and a shorter foil retained by Exchequer officials. During an audit, the pieces were fitted together to check the account. The museum catalogues the object as wood, under number 74.431.
Do not assume that every display contains both halves. The Science Museum Group explicitly describes its group, dated around 1440, as sixteen stocks only. A collection label can therefore tell you something a photograph might leave ambiguous: whether you are looking at a pair or at surviving pieces of several different records.
Three questions for looking closely
- What does the catalogue identify? Start with the object number and date rather than guessing an age from dark wood.
- Which part survives? Look for wording such as stock, foil or pair. Do not imagine a missing partner is present.
- What has actually been decoded? A general explanation of notches is not a translation of every mark on the object in front of you.
This approach also helps with wax seals on documents: identify the physical evidence before treating it as a complete account of an agreement.
Reading the evidence
The museum records establish the examples and describe the mechanism. We have not handled the objects, reconstructed their transactions or independently decoded their notches. The cover presents imagined teaching objects, so use the linked catalogues to inspect the surviving examples.
