Shilling.

Said to be derived from St. Kilian, whose image was stamped on the “shillings” of Würzburg. Of course this etymology is of no value. (Anglo-Saxon, scylling or scilling, a shilling.)

⁂ According to Skeat, from the verb scylan (to divide). The coin was originally made with a deeply-indented cross, and could easily be divided into halves or quarters.
