First of all Welcome to the CC Forum Fellow Michigander.
That is an interesting specimen I have not had the opportunity
to find one of those yet so I have not done any research on them.
But a buddy of mine that owns C.C. Coins in Kazoo
is always looking for them. I am not sure if it is because they
have a large amount of value or it is some kind of
Obsessive Compulsive Disorder on his part. Like my OCD with
Eisenhower dollars and 1883 No cents Nickels

I copied your photo of the no FG area and cranked up the
resolution in the one I enlarged and the contrast and color
in the small one. The field looks very smooth
I am not sure of the reasons we have the no FG's whether it is
die grinding or
Grease Filled Die.
But it is a valid variety listed in the
Cherry Pickers GuideNumber "FS-50-1972D-901" in the comment section of the book for this coin it says "This variety is not as well known as others"
Values Listed MS-63 $50.00, MS-65 $75.00, MS-66 $150.00
MS-67 $250.00 These prices are just very General Guides what you would actually get at auction may be a totally different matter.
But since it is in the
Cherry Pickers Guide PCGS will grade and Attribute the coin with the No FG designation which will definitely help raise the price you get if you decide to sell it.
and from what I can see from your pictures
without seeing the coin in hand. I would say that you have found a good one. Congratulations

Edited to add: If the coin is sold Raw, Not graded and attributed
I am sure that the as usual the price that can be gotten will
be considerably less than any price guide.
