MONEY
is of no importance whatever except in so far as it
prevents a spiteful debtor from playing an occasional
“ nasty trick ”’ on his creditor by paying him a large
sum in these coins.! If they had not been legal
tender at all under the law of 1816, they would
have been generally accepted just as much as they
are. If they had been legal tender for any amount,
they would not have been tendered for large amounts
any more than they are: in fact silver is seldom
tendered for amounts above gs. 113d., which is less
than a quarter of the legal maximum, and bronze
is seldom tendered for sums above 53d., which is less
than half the legal maximum.
The law of legal tender has nothing to do with
the value of the silver and the bronze coins. They
are maintained at the fixed ratios, 20 shillings, and
so on, to the pound sterling simply by sufficiency
of demand coupled with adequate limitation of
supply. When there is a demand for a thing it will
have a value until the supply becomes great enough
to reduce its marginal utility to nil : what value it
will have depends, given the particular elasticity of
the demand, upon the magnitude of the supply. The
value of the silver and bronze coins of the United
Kingdom is kept at the intended ratio because the
Government, exercising an absolute monopoly of the
manufacture of the only known convenient media
of exchange for small transactions, metallic coins,
supplies them only in the limited quantity appropriate
to that ratio.
To make this quite clear we need only consider
what would have been the result of insufficient
demand or excessive supply.

51d lady 4s. 10d. in coppers was quite within his rights. She
should have tendered 2d.. not asked for change for a five
shilling piece.
