why was a shilling called a bob

A shilling was called a “bob” in old British slang, but the exact reason is uncertain; several colourful theories exist, and none is universally accepted.

The basic facts

• A shilling was a pre‑decimal British coin worth 12 old pence, and in everyday speech people almost always called it a “bob”.

• The term “bob” is recorded in use by the late 18th century, first noted as cant (slang) among criminals and those around them.

• Over time it became normal, so phrases like “two bob” or “a few bob” just meant “a shilling” or “some money”.

Main origin theories

• Sir Robert Walpole link
  • One 19th‑century explanation ties “bob” to Sir Robert Walpole, Britain’s first de‑facto Prime Minister.

* As Chancellor and then Prime Minister, Walpole reduced land tax from four shillings in the pound down to one, so some writers suggested the shilling became nicknamed after “Bob” Walpole.

• Bell‑ringing and “ringing” money
  • Another theory notes that “bob” was already a term in change‑ringing (patterns rung on church bells), where a “bob” is a particular kind of change.

* Since “shilling” traces back to a proto‑Germanic word related to “ring” or “resounding”, some suggest a playful connection: ringing bells, ringing coins, and so “bob” might have crossed over from bell‑ringing slang to coin slang.

• General slang / unknown root
  • Many etymologists think “bob” may just be an old, short slang word for a small unit of money, similar to how “quid” arose for a pound.

* The precise linguistic root is considered **murky** , and modern coin historians often conclude that no single theory can be proven.

What people agree on

• Everyone agrees that:
  1. “Bob” = one shilling in traditional British money.

2. The nickname was firmly established by the 19th century and stayed common until decimalisation in 1971.

• What people do not agree on is the original spark for the word, so reputable sources usually list several possibilities and then admit that the true origin is lost to history.

Forum and “trending” angle

• In recent forum discussions, users often repeat the short answer—“a bob is just a shilling, like a quid is a pound”—and then debate the Walpole theory or shrug that “no one really knows anymore”.

• The phrase still pops up in modern culture (“a bob or two”, “bent as a nine‑bob note”), so curiosity about why was a shilling called a bob keeps resurfacing online, even though the honest answer is that the nickname’s exact origin remains uncertain.
