A few odd JFKs coin roll hunting

[Amwcoins]

The first 3 photos are a1974d no fg

the second is a 1991

missing a few things not sure why it's missing 

then a 1972 that I'm guessing maybe planchette damages or clad 

then a 1982p no  fg

Are these worth grades or being certified I'm wondering how that works

I'm only aware of three dates where the FG has been completely polished out on the dies, the 1966 SMS, 1972-D and the 1982-P

It would be very intersting if in fact you have some 1974-D unaltered no FG Kennedys

The 1972 where the outer clad layer has exposed the inner core looks 'etched' so I'm considering this one eviranmental damage.

The 1991 exhibits a 'clogged die' pattern and has no premium.

The 1982-P no FG would be cost prohibitive as MS examples can be had for $20

I agree with woodenjefferson on the 1972, 1991, and 1982-P no FG.   The '74-D may be grease filled too; really hard to say.  Neat find.  I've found some Kennedy's with the "F" completely missing, and just a faint outline of the "G," or vice versa.      

Searching rolls can yield some very pleasant surprises, and you've certainly found some- keep looking, and good luck!
