You can not have a class 7 doubled die (Modified Hub Doubling) as they can not be made with a single squeeze hubbing. A class 7 was made when one hub was used and then a different and modified hub was used the next time it was hubbed. The US Mint started experimenting with the single squeeze hubbings in the late 80s, and started using it on all coinage in 1999.Bob Piazza

I personally think the image is not clear enough.
Three most important things in coin photography: Lighting, Focus and Size.
For newer coinage, one has to change the mindset on what a DDO and DDR might look like.
They are not the same as coinage of 1995 and before.
In the mid 1990's the US mint changed the way they make the working dies.
The dies are made under a single squeeze technique using a massive amount of tonnage to make the image of the coin complete after that single squeeze.
In MY opinion, any coin that is subject to a single squeeze technique is by definition not a doubled die.
There are reports of coins after 1995 that are doubled dies, but in my opinion, all they appear to be is rolled metal from the excessive tonnage applied to the working die. In the older coins, if we see this shift, we call it mechanical doubling, mechanical damage or otherwise.
This approach should be taken in light of how dies are struck as well - they can be subjected to the same style treatment, but since some of these coins "look different" they are accepted as varieties. I personally will not invest in these newer potential DDO's and DDR's because, by definition, they are not.Last edited by MintErrors; 01-30-2022, 09:28 AM.Gary Kozera

THAT was my opinion. I am not here to prove anything to anyone. I am not making this a debate. Enough said.Gary Kozera
