The United States have three mints for the coin
age of money-one at PHILADELPHIA, one in North
Carolina, and the other at New Orleans-and al
though the two latter are called mints. yet they


may more Justly be considered as branches of the
parent Institution in Philadelphia, which is car
ried on in large and splendid white marble
building. built for the purpose. 1t was establish
ed in that city almost Immediately after the forma-
tion of the government. The coming of money
is not generally understood, and Philadel phia
paper has been at pains to collect an account
of the process Bullion is brought to the mint
in every form; amalgamation from the oar bars,
plate. Jewellery and foreign coin: All these present


great variety as to quality. The assayer brings
this heterogeneous mass into proper condition
and incness for coming, and returns the metal in
ingots or small bars. These bars, or ingots, are
then annealed to soften them for rolling; when
they are passed through the rolling machine,
worked by steam engine, and come out long
thin sirips-of the width and thickness most con-
venient for use. In order to reduce these strips
of metal to their proper size for the press, they
are drawn through nicely graduated drawing
dies" In the next place, they are passed through
the cutting press, which is also moved by steam,
and pieces of the true size are cut out The punch
moves so rapidly that one hundred and sixty pie
ces on an average, are cut out in minute. The
piecrs thus prepared are next put into the milling
mac chne, in which the edge, to afford protectlon
to the surface of the coin, is forced up. In this
machiDe, one hundred and twenty half dollars, or
five hundred and sixty half Dimes can be milled
in minute. The pieces of metal thus prepared
are then tested, as to their weight and, if found
correct, again sofened for the dies The stamp
ing machine is moved, also, by steam power.
The pieces are put into inclined tube at one
side of the machine, from which they reach the
coming dies in regular order, receive the impress
sion and fall into box below-npon the opposite
sde--a perfect coin ready for circulation. The
cnning presses are Of various sizes, to suit the
various denominations Of coin. The usual speed
of striking is sixty pieces per minute the hall
dollar, seventyve for the quarter, and ninety for
The dime. The mint, with few additional hands,
is competent to coin ten millions, half gold and
half silver, annually" -,@.
