A dog or a black dog was a coin in the Caribbean of Queen Anne of Great Britain, made of pewter or copper, typically worth 1½ pence or 1⁄72 of a dollar.
The name comes from the negative connotations of the word "dog," as they came from debased silver coins,[1] and the dark color of those same debased coins.
[2] Black dogs were also at times called "stampes" or "stampees", as they were typically the coins of other colonial powers—French coins worth 2 sous or, equivalently, 24 diniers—stamped to make them British currency.
For example, the Spanish dollar was subdivided into bits, each worth 9 pence, 6 black dogs or 4 stampees.
[3] Mary Prince's narrative tells of slaves in Antigua buying a "dog's worth" of salted fish or pork on Sundays (the only day they could go to the market).
