This is a tintype mounted as a CDV.  These were common
during the Civil War and for perhaps the ten years following
the war.  This one is good.  No red flags here.  Also, this
image might be worth $5-$10.  Faking one of these would
be like counterfeiting a $1 bill.

When looking at tintypes beware of really yellow images or
images that have strange coloring.  Sometimes they can
yellow from being varnished but often it is a sign of modern
work.  Again, this one is fine and all good tintypes are not
necessarily the same color.
