Nob

Nob is slang for head and dates, according to the OED, from the year 1700. The etymology is obscure but 'nob' is still used today in the British card game known as Cribbage, where 'one for his nob' scores one point for holding the knave or jack of the same suit as the turn-up card. ‘Two for his heels’ is the Cribbage term for two points when the turn-up card itself is a knave or jack. The use of 'nob' and 'heels' in this context derives from the days when the illustrations on royal playing cards were not reversible, and had both heads and heels. Playing cards with non-reversible illustrations were still being produced well into the 19th century. Nob is also slang for a person of some wealth or standing and dates, according to the OED, from 1755. Again, the etymology is obscure. It may derive from an abbreviation of 'nobleman' or 'nobility' , but this is not proven.
