Now all we need is an explanation of the key word
"chief" incorporating Webster's definition of
obverse and you'll see you are wrong. <g>

HINT: Chief...The most valuable and important part
of anything. Pete knew where this chip was from,
and Allan Myers had to ask.

The portion of a piece having the most [important] information
is the obverse...according to numismatics (which is
what we're dealing with) and Webster's definition.

Wasn't intended to be a hard one, Jim...just
answering a question with some questions....I hope.
