This doesn't jive with Alan Herbert's explanation, Struck Through Abnormal Objects, beginning on page 253 of his book, Official Price Guide to Mint Errors, Sixth Edition.

It is impossible to be raised when it is struck into the field. The surface of the die forming the field is the highest, flat surface and would drive the foreign material flush with surface.

yea, super rare.....

From paddy's site
"Definition: A form of raised doubling that develops in association with “grease strikes”. In this form of doubling, die fill of a smooth consistency coats the die surface and fills its recesses. The die fill sets and becomes very stiff as it pounds against many planchets. The layer of die fill escapes from its recess, migrates onto the field, and is struck into a planchet, leaving a raised, slightly enlarged version of the adjacent normal design element."

 

I don't know who wrote this, but I have a hard time accepting it.

"The die fill sets and becomes very stiff as it pounds against many planchets."

The grease doesn't set and become very stiff. Coin production doesn't stop long enough between strikings for this to occur. It becomes compacted and almost as hard as steel from continually striking planchets.

This process of grease filling a device doesn't happen "all at once". It is a gradual build-up and continual striking of planchets that causes it. It is highly unlikely that this build-up of grease isn't also impregnated with a small amount of dirt and debris which strengthens it just as small stones strengthen concrete.

The layer of die fill escapes from its recess, migrates onto the field, and is struck into a planchet, leaving a raised, slightly enlarged version of the adjacent design element."

Give me a break! It doesn't "escape" from its recess. It doesn't "migrate" onto the field. It falls out of the device onto the planchet in a split-second. How does this compacted grease leave a raised element when it is struck into the field? If this was the case, it would mean that the die does not make full contact with the planchet, and there would be a "crater effect" of planchet metal pushed upward associated with all strikethroughs.

It sounds to me like the person who wrote this definition did a lousy job of redefining some other published definition to avoid plagiarizing their work.

I'll stick to the published definitions of Alan Herbert!

I have not seen this book. I going to have Barnes and Noble order the 7th edition for me.. Thanks!

 

The 6th Edition was published in 2002. I wonder if any definitions were amended/added to the 7th Edition.

Chris

 

I wonder how long ago Mike wrote this and if he still feels that it is correct. I just can't agree with it.

 

What would PCGS do with this if i sent it in?

 

Grade it

 

Then return it to you

 

and say "struck thru grease" ?

 

They only write things at you

 

I believe that coin could be struck through feeder fingers.

 

I'm still hung up on the lines across the coin.

 

Well obviously the buildup of all that grease caused a thicker coin which didn't fare well in the final planer and belt sander phase of minty finishing.

Don't you know anything about the process?

 

PCGS had me send in photos of the coin, they are going to respond to me by tomorrow with how they will grade it. If they dont include the word 'doubled' or doubling...then off to ANACS i guess.
