The poet seems to mean that a barber can no more earn sixpence by his face-royal, than by the face stamped on the coin called a royal; the one requiring as little shaving as the other” (STEEVENS) . “If nothing be taken out of a royal, it will remain a royal as it was. This appears to me to be Falstaff's conceit. A royal was a piece of coin of the value of ten shillings” (MASON) . Seeroyal.
