1973-D Half Dollar ?

I don't know what all of those markings mean and I assume that they are just notes for the dealer or something like that. I could be wrong, but I honestly have no idea.

after looking at another 1973 half I am starting to kind of get excited a lot of the numbers and letters look like balloon font on this coin compared to the other coin. I also can for sure see a more rounded edge doubling on the top of the three and the bottom inside of the three. The N in IN GOD also has doubling on it pretty heavy. If this helps when I get back later I might post more pictures.

I sucks at detecting any kind of doubling, so take my opinion with a grain of salt. I have basically no experience with halves. From googling I would research the 1973d DDo-002 number as that seems to be more commonly cited.

Per this site: http://www.varietyvista.com/Variety....htm#_1973-D
There should be "Extra thickness on IN GOD WE TRUST, LIBERTY, and date"
There are also some other markers you can look for, but I don't know what they mean.

From a competing forum site I see a post where someone is saying "The 73D DDO-002, 003, 004, and 005 all have some notching on the top right of the you in TRUST". I can't tell from your picture and I'd need to see some examples of coins with and without this notching to be sure.

So not really an answer. Just some things to maybe research more if you can. If it were doubling, I'm not sure what type of premium (if any) it would command).

I am trying to work on the pictures sorry about that. Here are a few more of course they are not really showing what I want them too but I will keep working on it.
