The Presidential Dollar coin series features edge-incused inscriptions of the
date, "E PLURIBUS UNUM," "IN GOD WE TRUST" and the mint mark.
This is the first time since 1933 that incused edge lettering will appear on
U.S. coins struck for daily commerce.
The location for "IN GOD WE TRUST" will
move from the edge to either the front or back of the coin, beginning in 2009.
The law was amended in late 2007 after Congress was deluged with complaints from
the public about the location of "IN GOD WE TRUST".
Cutting-edge technology was developed by the Mint to apply the inscriptions
after striking on the expected high volume of Presidential dollar coins bound
for general circulation or Uncirculated Mint Sets. For Proof specimens,
the inscriptions will be stamped onto the edge of the coin during the striking
process.

"E Pluribus Unum", "In God We Trust", and the date, were moved from the face of
the coin to the edge, in order to open up
space for other design elements. Beginning in 2009, "In God We Trust" is
moving from the edge to either the front or back side of the coin, due to
pressure from the public. United States Mint

The location of the edge inscriptions vary from coin to coin on general
circulation issues because of the enormous quantity of coins sent through the
edge-lettering machinery at high speeds. If the time were taken to ensure
the dollar coins all entered the machinery in a standardized manner, anticipated
production demands could not be met.
The manufacturing process for Proof Presidential Dollars is considerably
slower, and results in the letters appearing in the identical spot on every
coin.
