"In the case of the letters s and d it is generally agreed that these stand for the Latin words solidus and denarius, originally Roman. The first use of these abbreviations to indicate shillings and pence given in the Oxford English Dictionary is dated 1387."

The 14th image shows, at the bottom of the pictured page, the price for a "Peck Loaf" listed as 2s. 6d. in a publication dated 1784.
As a reminder, the Victorian era began in 1837...
