One error the US has avoided so far ... or has it?
This is what happens when you use the same design for every denomination!
If you look closely, you'll see a double rim on the obverse since the die used is intended for a smaller coin, the 10 cent coin, not the dollar coin. Understandable when they are the same design for every coin.
Some people call this a double denomination but the 10 cent denomination isn't actually on the coin so this is debatable to me.
The US used to use the same design on many coins, especially for the Liberty Seated and Barber series. We even had the Liberty Seated Double Dime coin!
Did the US Mint ever use the wrong denomination obverse with the same design for a coin?

If I'm not mistaken, the same reverse dies were used on draped bust $2.50 and heraldic eagle dimes.

Great coins!
Love the James Stack coin! It's a dream coin for me.
The Hansen coin nice too. Love the clashing on it

Is the die not intended for one of the denominations? Or was that intentional?

Modern Quarter/Dollar mules are under a cloud of suspicion as to whether they are errors or deliberate fantasies.

I'm not positive. The coins are almost the same size, the designs are the same, and the press permitted it, so why not do it just to save money in the early days of the mint? There may be other such re-uses throughout the two series, but I haven't dug into it.

There are various "patterns" where dies of different denominations were paired together, sometimes for the sake of convenience and sometimes as deliberate fantasies.

Cool topic!
Wondering if there might be a few gold plated heraldic eagle dimes circulating back in those days similar to the 1883 V nickels.

You'd think so, but perhaps the difference in the obverse design plus the penalties for counterfeiting made it not worth the risk.

There are mules of coins of different designed paired together two famous ones
1839 small letters Rev bust half
1840 (o) large letter seated half (Rev of 1838)Some how they made some reeded edge bust halves with a Rev from seated halves
And New Orleans made some seated halves with bust have revs

Anyone else notice the Kangaroos seem to be moving in a circle?

Heraldic eagle halves and $10 gold are about the same size, so those reverse dies were also interchangeable. I don't know if they were reused across denominations. The quarters and $5 gold are 2 mm apart in diameter, so reuse there was less likely to work well.

The classic opportunity would have been a Liberty nickel Obverse with a Liberty $5 reverse. Same size and similar design. Never happened that I know of.

I believe that I see the same Die chip result in both the $2.50 and the 10c reverse...

These are known to be the same die. Look at the die state of the star below. It was used to strike quarter eagle, and then dimes.

Q: When does a collector become a numismatist?
A: The year they spend more on their library than their coin collection.
A numismatist is judged more on the content of their library than the content of their cabinet.1 -
There was a collection several years ago that dealt with the $2.50/ .10 pairings.

That's the one. Can't seem to find the Catalogue. Thanks.

It is a small dedicated collection catalog if that helps.
