I think most of us answered the original question. I didn't even see the modifications mentioned later. In fact, the stipulations added seem very contradictory to the original question, in my opinion.

In the original post we are asked if there are simply too many "extreme rarities" for any one card to stand alone. Then later we are told it would have to be a "special player from a classic set that is available enough to be collectible."

If a card is "available enough to be collectible" it is automatically NOT a Holy Grail card in my opinion. That's one reason the Mantle and Wagner are both NOT Holy Grail cards. Might be collectible and desirable, but a true Holy Grail card should be nearly impossible. Not impossible. But NEARLY impossible.

Maybe I have a different understanding of the term "Holy Grail" than most. I am unfamiliar with the legend that tells of King Arthur and the knights of the Round Table and their quest to find one of 80 or so examples of the Holy Grail.

Sir Lancelot: OMG! You'll never believe what I picked up in the last SCP Auction!
King Arthur: Wow! Sounds exciting. What it is? A one-of-a-kind item?
Sir Lancelot: Even better! It's a Holy Grail! I was the underbidder on the last 4 that came up for auction, but now I finally have a Holy Grail of my own!
King Arthur: Congrats, buddy! Yeah, I'm looking to upgrade my Holy Grail and there's a nice PSA 4 in the next online auction to close. Like you and I, the auction that's selling it is LEGENDARY!
Sir Lancelot: ROFLMAO!!!
Guinevere: I'd do just about ANYTHING to, I mean "for" anyone brave enough to find the only example of the only card of baseball's first superstar.
Sir Lancelot: Hey, um, I gotta split, Arthur. I'm pretty sure the Holy Grail I just bought was touched up and the images in the auction catalog were doctored since I bought it from SCP. I need to replace it. I think I'll head to the east coast to track down a lead on a Jim Creighton card I heard about. I know, it's no Holy Grail, but still pretty damn cool and far more important than most collectors realize. I might be interested in one of your Holy Grail dupes if I can't get the Creighton. Take good care of that wife of yours, friend, while you still can.
King Arthur: Take good care of my wife? While I still can? WTF???
Sir Lancelot: Um, what I mean is, uh, you never know what can happen in this crazy world. Look at it this way, if anything ever happened to you...or, worst-case, if anything happened to your wife, not like dying or anything, but if she wasn't around any more for whatever reason, at least you'd still have that Holy Grail of yours to keep you company. So you've got that going for you. Which is nice.
King Arthur: Okay, well, see ya, Lancey (said with Bush-like giggle). By the way, what the hell is "baseball" and where is this "east coast" you speak of?
Sir Lancelot (galloping off, voice fading): So long, sucker!

Aaaaaaaaaaaaaannddddd.....scene.

Anyway, I hope this little mini-play gets my point across: It might make you feel like a king to own what most consider a Holy Grail, but you're one of many, and the guy with the real Holy Grail is probably sleeping with your wife.

Shame on you, Corey!!!
