1972 D Half Dollar, No FG Question.

Over-polished die issue?

To me if you can see the FG in any direction then it is a FG. Do not get it graded either way.

No. From PCGS, A 1972-D No FG Half Dollar should show no traces of Gasparro's initials. Genuine No FG halves will also show weakness in other surrounding features, such as the eagle's wing, stars, etc. While absence of the FG initials can be picked up by the naked eye, use of a high-quality 5X or 10X magnifier is ideal - particularly for ruling out what may be a weak FG, which isn't presently a recognized form of this variety.
@Coinfrog The lack of "FG," or the initials of Kennedy half dollar reverse designer Frank Gasparro, is a glaring and inadvertent omission stemming from die abrasions and /or overzealous die polishing. This prominent 1972-D variety isn't the only No FG Kennedy half dollar or NO F - there are several kinds that collectors know about and probably others floating around yet undiscovered such as 1972D NO FG, 1973D NO F, 1977D NO F, 1982P NO FG, 1983P NO FG for example.

However, the 1972-D No FG is the rarest of these known. PCGS has graded a little more than 100 of these coins across all grades. That's a tiny number for a modern coin and serves as further evidence of this variety's tremendous rarity. A circulated example in XF40 runs around $275, with uncirculated specimens starting in the neighborhood of $425 for an MS60 specimen. Only a couple dozen of these coins reside in PCGS holders with Mint State grades, the finest a single specimen in MS66. Values soar into the four figures for any specimens north of MS62+ so yes to grading this particular one if found.
