One of the most interesting coins in the
Lincoln Series.  It is both a repunched
mintmark (RPM) and doubled die
obverse (DDO).   This is a perfect
example of class III "design hub
doubling".  In 1960 there were both
small and large date designs.   In this
case a small date hub was punched
over a large date hub.  

Doulbling can be seen easiest on the
date.  

The extra mintmark can be seen north
and slightly west of the primary  
mintmark.  

Early die state example are much more  
desirable
to collectors than later die
state examples.  Late die state examples
exibit die scratches most visible under
IN GOD.

Three different class III doublings exist
for the 1960 proof.   One exists for the
1970 S proof.
