While the state coins money, and charges no seignorage, money will be
of the same value as any other piece of the same metal of equal weight
and fineness; but if the state charges a           for coinage, the
coined piece of money will generally exceed the value of the uncoined
piece of metal by the whole seignorage charged, because it will require
a greater quantity of labour, or, which is the same thing, the value of
the produce of a greater quantity of labour, to procure it.
