1971-S Eisenhower Dollar Hub Or Master Die Doubling

Those are mixed pictures of the obverse and the reverse, Liberty( that R) and IGWT are on the obverse.

It is probably both a DDR and a DDO

Full pictures of both sides would be helpful

or maybe this one

Thanks John1, jbuck.

Thank you Gincoin43 for the links, your first link is very useful and comprehensive.

Reason I questioned it is because this one with having the doubling on both OBVS. and REVS. is not listed/attributed anywhere, the notching are indication of Hub doubling to me, but since there are numerous master die doubled Ikes I wasn't sure.
I will try to post a full pic of reverse and the obverse but the problem is the coin is still in the original mint Cello wrap and most likely the glare will interfere with details!

Not that I noticed while I was taking pics. will look again when I get home from work.

Before celebrating, you might want to read what Wexler had experienced on the 1971 Eisenhower dollars:

There were issues on these. After reading, you might see if this one is listed or not.

Thanks coop, I have read Wexler's article and that was my main reason for asking for opinions, did not find any similarities to his descriptions particularly of the R of LIBERTY, W of WE and the notching on the EPU, given majority of the described master die doubling have usually referred to the doubling/notching on top and upper portions of the devices, in this case I think the notching on the lower leg of the R, doubling on the I and B are quite convincing.

And it also seems Wexler's and Brian's finding were particularly focused on the Proof specimen as it is evident n his article and the referenced images for the DDO / DDR's without any examples of the Business strike specimens!
Who knows

Save it anyway. But if there is an issue with proof coins, the same master dies created business strikes and proof dies.
