FACTS ABOUT COINS.
MANY MISTAKEN IMPRESSIONS
HELD BY THE PUBLIC.
Impossible 10 Test Genuineness by the
Ring = SReeding" Prevents
Any of the Metal Being
Scraped on.

MANY persons have a mistaken idea
about throwing a coin to test its
genuineness." says Captain Tom HaAs
Of the secret service in the Indiana
polls News. Throwing a coin is not
an absolute test for the reason that
q great deal Of our good money will
not ring at all, while some of the
bad Will There are several things
that will take the ring out Of a genu-
inc coin. One Of these is a possible
flaw in the metal.
1T sometimes happens that in cut
ting out the disks Of metal from
which the coins are made there viii
be flaw or a crack in the sheet. II
this is true, It matters not where the
flaw is. whether II be unseen or along
the edge, where it may be discovered
by close inspection, it will destroy
the ring OF the piece. This ring is
caused by the small crystals or
globules on the inside OF the metal,
the vibrations Of which cause the
sound we SO like to hear in our
money.
IF there is any flaw or small fs-
sure which destroys the connection
between these globules the ring win
cease. There are also other reasons
for a coins losing its sound. Should
a quantity of coin be left in a safe

crystals will mslt and the rhythm viii

AS is generally known. our coin
Is not absolutely pure and does not
contain the amount Of silver repre-
sented by 1t. Should there be a dol
lars worth Of silver put in the stand
ard dollar It would be almost as large
again as II is now and most incon-
venient to carry. especially In a large
quantity. There are 412.5 grains Of
silver in our standard dollar, which
is 900 per cent pure. The rest is
alloy and is put in TO harden the coin.
The marks around the edge Of tbp
coin called the .reeding' are put there
to keep persons from removing any
OF the metal. Should any attempt be
made to scrape Off the silver II could
be detected Immediately from the
SCARED 'reeding' II will also be OBJ
served that around the edge OF a coin
on both faces there is a narrow,
raised rim somewhat higher than the
engraving. This is to protect the in
scription from being destroyed by the
friction Of one coin on another.
