Looks like MD to me. All the doubling has the shelf-like appearance. I also checked LCR and there is no DDR listed for 1996.
Nice pictures! Someone should do a guide to DD vs. MD...and use your pictures for the MD part (very nice).
I really hate to say it, but if you have to ask it's probably machine doubling. Trust me, most double dies will really jump out at you.
For beginners, asking whether a coin is a doubled die is all part of the learning experience. Finding a doubled die takes a lot of trial and error, and I think that someone asking whether a coin is a variety or not doesn't really have anything to do with the likelyhood of the coin in question being collectable.
