2025-W ASE Proof Defect

Just learning,

Thanks Jbuck.

I received a West point ASE not long ago and while checking out the coin was noticing a Small die chip or ? at the base of the Letter " Y ",on the Obverse.

It appears to be noticeable to the naked eye, Not sure if it is Incused or raised( its small ) I do Not post pictures, I appreciate your follow up question. If it is there, You Will see it...

Anyone have any idea as to How long Approx a ASE Die last in service .

If I can help in Any way, Please, Let me know, Best wishes, MD

My pleasure.

My thoughts center on the 2008 rev of 2007.
The reverse die didn't get changed when they began production because it was a relatively new die. I think they ran that die until it was in need of replacement, not because they discovered the mistake. The pop of the incorrectly struck coin is approx 45,000. Makes me think it was only used for roughly 5000 2007 coins and they run the dies for 50,000. Based only on what I've heard and a wild but calculated guess.

I was just speaking in round numbers. I still think the answer to your question is 50,000

I think you misunderstood what I said. You asked this question:


My understanding on the 2008 rev. of 2007, is that the reverse die that produced the error had been recently replaced prior to the end of 2007 production. No one caught that the reverse die needed to be changed due to the (minor) design change.
EDIT The US Mint didn't even know the error was made, a collector noticed it, this would have been well after that die had been replaced.
So a certain amount of 2007 ASEs were correctly made with it, then kept using the die in 2008 until it was replaced at the normal interval.
So what I'm suggesting is that "roughly" 40,000-45,000 2008 ASEs were made with the 2007 reverse die, that the answer to your question "how long a die will last in service" is 50,000. Not how many 2008 burnished were made with the 2007 reverse. It's how many total were made with that one die, correct and incorrect.
After hearing about the error, the Mint went back to find out what happened. They even know the die number that was the cause of the error. They keep track of all that stuff and after they found out, they knew exactly what happened. Wonder if the person responsible kept their job? Someone messed up.


The mint has stated the exact number. Again they keep track of those dies and they know exactly how many were struck with it. I can look it up if you really want to know.
Again to sum it up, it's a 2007 reverse die they used in late 2007. They changed the design for 2008, but they didn't replace this one relatively new die. They used in in error in 2008 until the end of it's service life, never realizing it should have been replaced at the beginning of 2008 production. They didn't know they messed up until a collector like us noticed, months after the die had been replaced.

Boy, did this topic get way 'off topic'..

Not if you understand why the question was asked.
