25C Proof Bicentennial Struck over 1C Denver

Not my Mint Error..
But simply amazing!

I wanted to share this amazing Mint Error Discovery story done by Mike Byers
https://coinweek.com/dealers-compan...al-quarter-overstruck-on-denver-lincoln-cent/



Quote - "This discovery mint error is fascinating since it combines rarity (unique), quality (Proof 67), history (Bicentennial one-year-only design) and intrigue (the only known Proof U.S. coin that shows mint marks from two different mints). This enigmatic and unique U.S. Proof mint error belongs in a major collection of the finest error coins or in a collection of Bicentennial coins." Closed quote

Very cool

 

Anybody here thinks that might have had a little help from a mint insider?

 

No way! (maybe)

 

I wonder if this is related to the other "enigmatic" proof errors from early 70's (1970-S quarter struck over a 1941 Canadian Quarter anybody?)

 

It probably leads back to the mint managers Black cabinet. I wonder how many of these types are really out there?
Seems like a bunch of Tom Foolery to me. Let's see a struck cent that found it's way into a hopper filled with Quarter planchets.

Still a cool looking coin!

 

Gack!

 

That's a one in a million. I wonder if there is more like it.

 

When an improbable "error" coin is discovered, it means that there will soon be a multitude of sensational youtube videos, and click bait articles. Get ready for a bunch of new members, asking if their PMD or environmentally damaged quarter fits the bill for this particular error.

Edit: Don't forget the blurry and ambiguous photos that the OP will latch onto in false affirmation of their opinion.

 

If there *are* more like it... I have caveman vocabulary.

 

Without question.

 

very cool and unique.

 

Very nice looking error.

 

Accidents do happen.
But when it is a proof coin, it seems like it was done intentionally.
As, the extra examination of the proofs before they go into sets, this
coin should have rightfully been destroyed. And since it probably didn't
come from a proof set, that means it was taken out of the mint illegally.
Speculation yes, but that's most likely what happened.
I realize it is graded and slabbed, but to me it is an illegal coin.

 

Randomly throw a US penny into the process and have the letters around the rim of a quarter line up almost perfectly with the circumference of the penny rim seems to be virtually impossible. The inside radius of "United States of America" is so very close to the outside radius of the US Cent. As is the date on the quarter. To me, it almost looks like it was done on purpose. Therefore, it would not be an "error". JMO

 

If that was a GENUINE inadvertent error then there would be up to the die run
(?50,000 to 250,000?) of specimens that show evidence of die clash damage from the original cent. The earliest ones would show the most detail. Since none have been reported this most likely was created AFTER all of the proof coins had been struck and before the dies had been defaced. The experts can describe the process more cleanly than I just did.

 

It had to have been done intentionally.

 

The cent should not be hard enough to leave any kind of a clash on the dies.
The dies are hardened to strike 100's of thousands of planchets.
Clashes happen because of die to die contact.
