Double Denominations

I honestly cannot think of any other way - besides intentionally funny business by Mint employees - how a coin already struck by a set dies winds up being struck a second time by dies from a different denomination.

The only other way I can think of is that after being struck inside the striking chamber, a struck coin somehow isn't fully out of the chamber and manages to be stuck in there somewhere and somehow. It would still have to be stuck in there while dies for a different denomination are replaced, and then would happen to come loose, fall back down into the Striking chamber, and become struck by different dies at the exact time a planchet meant to be struck by those dies failed to come inside the chamber. This scenario seems ridiculous. Plus there would also be an additional planchet now in the Striking chamber, and thus the previously struck coin would not have a dead-on strike from both dies; it would result in a strikethrough indentation, right?

What other ways could double denominations be created without someone purposely throwing a struck coin into a pile of planchets waiting to be struck by different dies?

I prefer the term "Mint Employee Assisted"

Also.. If you notice it's larger on smaller coins.
- So Quarter struck on Nickel, Cent and Dime
- Nickel struck on Cent and Dime
- Cent struck on Dime
It can't be the other way around because the larger coin won't fit into the smaller chamber.

 

This seems like a legitimate explanation to me but I do not know the process inside and out.

 

I actually just found that in my book from Fred Weinberg right after I posted my question

For some reason I thought the bins for carrying away struck coins were not also used to transport unstruck planchets, thus would be ruled out

 

"the other way around" are assisted
errors -

As long as they are not current coinage
(dated 2017 or 2018), in general, the
Mint/Treasury isn't interested in them.

 

Hi, Fred!

What do you mean the Mint is "not interested" in them? Do you mean they don't demand them back?

 

I am pretty sure I saw a dime on cent planchet before

 

I don't doubt it..
Here are a 1 Cent on $1 Sac..
And a 1 Cent on Quarter


I took these pictures at the Philadelphia Show... Yes ANA show

 

Those two coins above were taken
at my table at the ANA.

Those were made on purpose, right
after all the publicity about the Sac.
Quarter Mule came out.

There's 8 sets known, so I assume there
are probably 10 sets total.

 

Unless it is a $1M Aluminum Cent......

 

You okay with converting publicly owned assets to the private estate of a former government official? 'Cuz that's what that 1974-D thing was. In my state, we put people in prison for that.

 

Unless there is a current employee stealing
coins, ('current leak') the Govt., again, in general,
is interestedin 1933 $20's, 1964-D Peace Dollars, and
1974 P & D Aluminum Cents.

 

I am pretty positive. Was slabbed by PCGS for several thousand on eBay. I will find it.

How did they fit in the much smaller collar? Those coins aren't even bent.

 

They were hand-fed on to the collar.

 

Ahhhhhhhhh

 

Not sure what made you think that I was but, no, I am not any more okay with that than I am paying tens of thousands of dollars for planned errors made "the other way around". I am surprised they carry that much value knowing how they were made. Demand I guess, like the Wisconsin extra leafs?

 

Demand is about marketing.
Supply is about crime.

What could possibly go wrong, right?

 

Think I'll hang on to my David Carr '64-D.

I don't understand the context of why these were intentionally done. Were they sanctioned by the Mint, or was it done by a rogue Mint employee? If not sanctioned, why weren't they destroyed?
