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.
