Is This A Double Die 1988-D Nickel?

Thanks for the quick response John! Sucks to be wrong, but you gave me something new to research - DDD. Many thanks

Note how all areas of the devices you are looking at are affected towards the closest rim? That is die wear. Not die doubling. On a doubled die the spread is on the centers of devices. While on this coin it looks like Machine Doubling, it's not. DDD shows on the devices in the direction of the closest rin, Machine Doubling is in a direction seen often as a single direction. I'd save this coin as an educational piece to show to a new collector as difference between the DDD vs MD. I'll be adding your images to add to my educational files.

I'm honored to have my nickel in your educational files, coop! Thanks for the thorough and detailed response, it helped me understand the DDD much more!

Nice example and explanations. It's always good to have a reference point.
