any case fall below that of the gold in the sovereign
where the possibility existed of turning the coin
into uncoined gold by the simple process of melting.
So the effect of seignorage is to keep the value of
the coin always between the metallic value and that
value plus the seignorage, and in progressive and
even in stationary periods to keep it at the higher end
of this limited space.
We must be careful not to be confused by changes
in the mere form of the transaction. For a person
to take raw material to a manufacturer to be made up
for himself, and remunerate the manufacturer either
by letting him keep a part of the product or by paying
him money for the service rendered, was once a
common method, but is now obsolete, surviving even
at Government mints, if at all, only in name. Gold
producers do not now bring or send their gold to a
mint and receive back the same gold less seignorage
and other charges, if any, but sell their gold to the
mint (or a bank which acts as its agent) for money
paid to them, and they regard themselves, like other
producers, as receiving a price for their product.
So there are ““ mint prices,” prices given by the mint
for gold, and when a seignorage is exacted, it appears
in the form of a difference between the mint price
of an ounce of gold and the amount of coin made out
of an ounce. When, for example, the mint price of
an ounce of ‘““standard” (i.e. 4} pure) gold is
£3 17s. 103d. or £3-894, and that ounce is coined
into £3:894 sovereigns, this shows an absence of
seignorage : a seignorage would be introduced by
the interposition of a gap between the mint price
and the amount of coin made out of the ounce,
e.g. a lowering of the mint price to £375 per oz.,
while the ounce continued to be made into 3-894
sovereigns, would yield the Government a gross
seignorage of £o0-144, or 2s. 103d. per oz.
