The young collector will not be long before he learns that a large
number of the coins exposed for sale in shop windows are false, and
at first he may be a little discouraged by finding that he is himself
quite unable to discriminate between a true coin and a false one.
But let him not despair. He will in time, by careful observation of
undoubtedly authentic specimens of the class which he has selected for
study, gain a kind of instinct which will enable him to detect the
modern imitation at a glance, even though he may not always be able to
explain his reasons to the uninitiated.
