MAIL, or Maille, in our old writers, a small kind of money. Silver halfpence were likewise termed mailles (9 Henry V.). By indenture in the mint, a pound weight of old sterling silver was to be coined into 360 sterlings or pennies, or 720 mails or half pennies, or 1440 farthings; and hence was derived the word mail, which is now vulgarly used in Scotland to signify an annual rent.
