Double Dies in new 2002 clad proof sets?

Post by Skip Meiste » Tue, 07 May 2002 05:29:26



Hi,

I got my 4 clad proof sets from the mint subscription yesterday.  While
looking through them, I noticed something looked *slightly* amiss.  I first
looked with my loupe and then with my binocular macroscope and it appears
that 2 of the Mississippi State Quarters ( best coin in the series so far in
my opinion) have a slightly doubled E Pluribus Unum.  Is this possible?

I also looked closely at all of the sets and 2 of the Louisiana State
Quarters appear to have the words Quarter Dollar doubled on them.  I may be
nuts, but it would be nice to have others look and see if I am making a
mountain out of a mole hill or just seeing double. :-)

Proof coins are struck more than once at slow speed to bring up the
design.  It's likely that any doubling you see is a misregistration
between strikes, commonly called machine doubling or strike doubling.
In order to determine if there is actual die doubling, a close-up
picture of the doubled feature would be required.  The easiest places
to tell die doubling from strike doubling is at the corner of
something.  Concentrate on the "E" in EPU and see if you can determine
if it was hit by the die twice, in which case the secondary image will
be larger and misshapen, or if the hub hit the die twice, in which
case the secondary image will be the same shape and size as the
primary, but just a little out of alignment.
