Huge Double Struck Proof Ike on Quarter Planchet Error

Just ran across this beautiful double struck Ike. Given the diameter, I was very surprised that this is done on a quarter planchet!
I like keeping track of a coin's provenance and this is attributed to Mike Byers.

Sure is a beauty! And likely an expensive beauty!

Proof, no less!
Yes it is! I just added it to the title since it's so notable!
Do you think this an intended error ?
If that was a quarter planchet, it must be as thin as a runway model.
You really do have to wonder about how something like that ever made it out of the mint.
I was about to say I bet you could shave with it! Pretty Cool!
Mike's coins are on a different level
That is a simply marvelous error coin!

For some reason Ike and the reverse looks better in a quarter size than
the huge dollar plancet

Interesting for sure although how a quarter planchet fed into a 50 cent press is tough to accept as a freak occurrence. IMO. Peace Roy

Yup. It had help at the mint.
Worry is the interest you pay on a debt you may not owe.
That Ike is a dollar coin rather than a 50 cent coin.
Worry is the interest you pay on a debt you may not owe.
That is one dramatic error
Proof coins are the finest quality of coin produced by the United States Mint. The term "proof" refers to the coin's finish. Proof blanks are specially treated, hand-polished, and cleaned to ensure high-quality strikes. The blanks are then fed into presses fitted with specially polished dies and struck at least twice. The coins are then carefully packaged to showcase and preserve their exceptional finish.

Perhaps it was made with Dr. Berry in mind, but he never bought it because somebody wised him up.
Who did wise him up, anyways?
I wonder why the dies were so tilted relative to each other during the second strike? The first strike happened with the quarter planchet off-center in the coining chamber, up against the collar at about 2:30 o'clock. That gave it a raised rim and some reeding in that area. During the second strike that rim and the reeding were mushed out, but the OD WE/ ST from the first strike is virtually untouched, as is the original Moon on the reverse.
Someone messed up, a quarter is smaller than IKEs head so that was a half dollar, some other type planchet, or struck more than twice. I would imagine it was weighed? Fred?
Ok, so the double strike makes sense since it is a proof. The coin was struck once, and then the coin moved because it did not fill the collar.
Now that I think about it, it would probably be odd to have a proof coin struck on a smaller planchet that was not double struck like that,

I have to wonder if the dies clashed at some point. Any regular ones out there with clash marks?
That is a amazing coin..... we likely will never know the real story behind it's creation.... Cheers, RickO
that is cool
lots of 1973 dated errors our there that certainly appear to have been "made"
I have some in the safe

That's part of what makes collecting an enduring hobby. There are just some mysteries out there that persist over time.
“know,” or “admit?”
That depends on who the "we" refers to
Very interesting. Do we know why they are just coming to market now?
I don't think we can rule out an accident. Isn't there a plausible explanation for how it could be an accident? The wrong planchet just got mixed in with the proof dollar plantchets.
You are the expert on the minting process, could this not have happened? Please explain, I respect your expertise and would like to learn more on this.

When you flip an honestly-balanced coin, the odds of heads or tails are not 50-50 because there is always the slight chance that it will land on its edge and stay there. Call the odds 49.9999 to 49.9999 or whatever they actually are after performing 10,000 coin flips. I never tried it.
This coin was made in a U.S. Mint from U.S. Mint-made dies on an official U.S. Mint planchet. It is possible, which is why it is certifiable. It is also highly unlikely, but you have to give it that benefit of doubt.
That said, the flood of astounding Proof coin "errors" from the 1968-1976 (or so) era is somewhere in the neighborhood of the statistical equivalent of having 100 coin flips in a row come up "edge." I have gambled in casinos and I have a tolerable understanding of "odds." For this reason I do not consider this coin to be an "error." It is a "Mint Sport," to use an older but more accurate term.
"Mint Sports" can be collectible. The Judd catalogue is full of them. That does not mean that they should be called "patterns."
That looks great. It reminds me of a D Carr invention. Great find
Best place to buy !

I made the case to @MrEureka a while back that it would be nice to classify fantasy coins (aka pieces de caprice, "Mint Sports") separately from "patterns" but he said separating them would cause too much confusion.
Perhaps the situation is similar with "errors"?
It's not so much that it would cause confusion, but that there are too many situations where the only way to know if an error was intentional would be to have been there when the coin was struck. (With patterns, it's more about motive than intent, but the cataloging issues are pretty much the same.)

Thanks for the clarification. It's an interesting area and I wonder how many can be definitively classified as "Mint Sports" as Tom calls it.
Or test them for traces of crankcase oil...........
If the odds are that this coin is 'mint sport' then are the odds in favor of it being property of the U.S. Mint ?
Here's what a single struck quarter planchet looks like for comparison. I've added the proof slab image here again for comparison:
Comparing the size of the two coins makes me wonder if the proof Ike may have been struck on a planchet punched from quarter stock but larger than 25¢ ? Awful lot of detail on the proof for a quarter-sized blank.
this is what I was referring to - if you place a quarter on an IKE, not cover the head. I did not measure or get specs on thickness, to tell if half dollar planchet on quarter stock. (not that any of this takes away from cool error)
I wonder if PCGS determined this was a quarter planchet by weight? Or is it possible that this is a half dollar planchet?
If this is indeed a quarter planchet, I think this makes it an even cooler error. It means some how the quarter planchet had to be enlarged prior to the 2 strikes seen.
I cannot fathom that any certification service would be so careless as to certify an off-metal or wrong-planchet error without weighing it!
