Sent To PCGS But Not The 1972 50c DDO?

I am not very familiar with the half doubled dies but know they are known for very common Machine Doubling. That being said, I see what I feel are "splits" in the serifs, not Machine Doubling. I looked at the existing doubling on Variety Vista and Wexler and do not see something that works, not even the doubled working hub. From what I can see, this could possibly be an unknown doubled die and why PCGS did not label it. If I were in your shoes, I would send to one or both of the attributers I mentioned, and if it gets listed as a new variety, send it back to a TPG with the letter so you can get it put on the slab or just label the slab yourself. Just so you know, odds are good that ANACS may be the only grading company that will label it with a brand new listing.

Good luck!

I do not see it being FS-101. The splits on TRUST are very extreme on FS-101 and I do not see them at all on yours.

The other I called a doubled working hub is actually series doubling, which may be from a doubled master die, which is more worthless than a doubled working hub, there would be millions of them out there, but think yours is different than that too, so possibly a new doubled die. They do not show much for the series doubling on Wexler though so not 100 % on that. Maybe someone more knowedgeable will chime in, there are some good Hald Dollar folks here.

Well I guess it's worth at least .50 if you don't take inflation into account.

Any chance that you can get a few images of your coin (nice close-up images) of the doubling?

As makecents says, the doubling on the FS-101 is strong in particular places. Notably, there are clearly defined splits along the bottom of TRUST.

I don't believe your coin is showing Machine Doubling. That looks like hub or master doubling. The Mint had multiple master die in use for Kennedy halves during that period, showing an array of minor doubling. Several of those flavors are documented on Wexler. In fact, the rounded top left splits on IN GOD and WE are very reminiscent of the 1976-S silver business Strike Doubling, which is also master/series/hub doubling.

Doubling on Kennedy half dollars can be really confusing. There is a mix of series, hub, die doubling. Often the specific doubled dies will have been manufactured with doubled hubs, resulting in even more confusion about what doubling is die-specific and what doubling is shared among many dies. It is only by carefully listening to folks like atrox here that I have even begun to get a handle on Kennedy doubling, and I am still a beginner in that area.

Thank you, BrandMiester, I'll check Wexler for that info. I'll end up super confused, I am sure, but at least this is fun.

Thanks guys, I could not remember his name but knew he was the go to for these.

I think your half dollar would be series doubling, SDO-001. In James Wiles book, The Kennedy half dollar Book, An Attribution and Pricing Guide, he says for the description: "The new obverse design introduced in 1971 was used again in 1972. It features an emphasized tail of the R in LIBERTY which hides the hair strand. Other letters of LIBERTY were also strengthened. This design is also Master Die Doubling and because the design with doubling was used again in 1972, it is designated as Series Doubled. It has a light spread on the Y of LIBERTY with rotation of the IN of IN, TRUST, and E and T of LIBERTY, Strength of doubling will vary depending upon hub and die state." James Wiles is the go to guy for Kennedy halves contact him on Variety Vista to see if he links it may be a new listing.
I also see some MDD (Machine Damage Doubling), like on the 7 of the date or on the N of IN in your last posted photo. I don't think your half could be the 72 DDO-001, I think the little bit of doubling I see would just be minor.
