Fearing a trick question where something else has the same design, I want to say it's the 2006 SF Mint commemorative dollar, but the coin in your photo looks to have a slightly different S mintmark, if not other subtle differences I'm not noticing on a cursory first glance.
Alright, you guys are too good..... Congrats @FlyingAl and it's only your 7th post...Nicely done....You nailed it. It is indeed the 2006-s SF Commemorative Dollar. I guess it was only a surprise to me! I saw the coin last night for the first time, never knew it existed! Cool coin!
You guys are too good.

That would be the 1955 Lincoln Cent doubled Die Obverse! Too easy! But easy is ok.....I need to start with the basics. My thread quickly went PHD level above with the post by @ErrorsOnCoins
Although that guess was also kind of wrong because it wasn’t on a cent planchet but a missing clad layer. San Fran would still be ruled out because they only struck the silver versions though.
Careful with that resource your're using, Jim. They have the correct photo for Judd 1550a, but have it labeled as Judd 1550, which actually has a different reverse design.
Wasn't familiar with the reverse on this variety, so I had to look at some images. Looks like all accented hair Kennedy's have the RDV-001 reverse with straight G, with characteristic circular lathe lines visible in the devices and weakness/breaks in the rays (under the eagle's chin, for example). Are there other good pickup points for this reverse?
Yes that is it! The best way to identify it is the rays, but it looks like you have all of the pick up points that I use, one other one is that the tops of the shield will be rounded instead of flat. You do have to watch this one because it is not unique to Accent Hairs, it seems one non Accented obverse was paired with a reverse of this type, leading to the "Straight G" variety.
I remember going there as a kid in the early 80's, when it was open to the public. They had a press there and you could pay to strike your own medal, which I still have somewhere. I also bought a 1976-S 3-pc bicentennial proof set from the gift shop that I still have.

Expand your quiz to other coins identifiable by only seeing the reverse...

We had a Young Numismatist swoop in and called it, right out of the gate!
'56
OK, Let's play.
That is either a 56-s, 58-s, 59-s, 0r 60-s seated lib dime. Right?
Yes, @fathom already got it because of the huge mintmark: 1856-S [From the late great John W. McCloskey collection]

FlyingAI, how did you know this was a "P"?
Lucky guess. I ruled out San Fran because they didn’t strike any cents in 76 and I had a fifty fifty shot lol.

Although that guess was also kind of wrong because it wasn’t on a cent planchet but a missing clad layer. San Fran would still be ruled out because they only struck the silver versions though.

That is correct! You can tell it's 1973 because of the large "FG" initials, and that it's an S because it is proof.
Alright I think I’ll go now. Tough one, gotta really know your Kennedy’s.
