No - A doubled die originates from the die that was used to strike the coin. It is the die that possesses the design doubling characteristics...
All the more reason I lean towards NGC having prior knowledge the coin was fake before examining it. Although not an ordinary occurrence - is it...
All I am suggesting is NGC may have had prior knowledge the coin was counterfeit before examining it. Which would allow them to examine this coin...
This coin was classified as counterfeit because it exhibited an undocumented die gouge? Are we to assume that all 1884-S Morgan die pairings and...
To be honest - I am still stuck on reconciling the difference between a punch vs. a hub. From what I have gathered thus far A Punch is a tool...
The State Quarters - well probably not many people actively putting collections of these together now; but I am fairly sure there are more...
I want to emphasize what I posted in this thread earlier - "Gives me indication it may be possible to identify all 1881-O obverses by mapping...
Yes rotation of the star punch would provide me with a different result. But that really is the whole point. The rotation of the stars may deviate...
I agree the diagnostic is very difficult to see with the coin in hand using a magnifying glass but substitute using an image of the target coin...
Here are CAD tracings of the two different coins in my post above. There is deviation in the positioning of the six design elements relative to...
[ATTACH] [ATTACH] Interesting - I am working on the same type of thing using CAD but not just for VAMs but all coin issues. Instead of...
Mont - thanks for the compliment. I don’t mind you using my post for your coin club newsletter but I would advise against it. It is based on a...
It would take 4 triangles to locate each specific digit of the date but I think two would be sufficient enough to differentiate one die from...
I am not trying to change definitions. All I am saying is it never occurred to me that a requirement of a Hub is it had to contain the whole...
I have always thought of a punch as a tool which utilized a striking force to transfer a design element and a Hub as using a squeezing force....
So theoretically every 1819 obverse die could be identified using two[ATTACH] triangles with the base of both originating from the center of the...
Thanks Condor that clears things up - For some reason I was thinking the N# identified the Obverse Die and the R# identified the Reverse Die. So...
I am venturing into new territory here – Large Cents that is. Alan Turing is not returning my calls and I need some help cracking the Large Cent...
I considered the idea of the die manufacturing process originating from a hub. I lean against it because an on an engraved hub it would also be...
In 1836 the Mint acquired the French Portrait Lathe. Prior to this time the die manufacturing process did not originate from reducing a galvano to...
