I quickly checked variety vista and there is only one DDR in the 1980s...1989-P. That is at the level needed for CONECA to be satisfied with the doubling. The coin you have is not listed on variety vista, meaning , more than likely it is something other than a doubled die, in my opinion. Machine doubling and other worthless doubling happened a lot, so those are a possibility.

Could it be a new discovery ? I do not believe so. A working die strikes approimately a half million dimes before retiring the working die. That means there are many others of this dime out there. I am pretty sure if it was a doubled die, it would have been listed a long time ago.

Doubling that appears lower and shelf or step like is typically worthless doubling. When working dies are doubled with multiple impressions, they are done with the same amount of pressure, and each should look pretty close to same height in the affected areas.

You can read more about worthless doubling at https://doubleddie.com under the worthless doubling link. I also have an article in my signature.

The doubling is MUCH lower and step or shelf like. In my opinion, its worthless doubling, probably machine doubling. Have a look at the first post in my signature.
