Here is a second 1955 Double-Die Lincoln Cent in PCGS 64BN.  Both sides exhibit near gem surface quality and originality which meets CAC expectations.  The cartwheel luster rotates across the full surfaces under the light, with no major detractions.  Deep chocolate brown tone with some hints of color especially nearer to the edges, no ugly carbon spots or large digs that some of these can display.  If one peruses the PCGS TVs for this example, be aware the color on these images is a little lighter brown than what we observe or show above, but all other surface qualities are accurate.  Simply stated, a pq example in MS64 that are hard to find.
 
This coin is approved by CAC.
