At the very least it's a MAD.

Nice find on the MAD. The doubling is MD.

Thanks for replying, but here is another picture of a stereo microscope, which, I think, looks more realistic and from this picture do you also see MD or else. thanks.

It does look way thicker to me from here or I am probably wrong again.

I wish I had Coops image of the 3-D hand drawn examples of Doubled Die vs Machine Doubling. Its hard to explain with just words. The date that is doubled has to be stick up as high away from the coin as the "normal" date. Notice how the part you think is a doubled die is only half has high as the rest of the date. A real Doubled Die is just what the name implies. The doubling is on the die itself. It is part of the design. If it is flat and not has high off the face of the coin as the rest of the date/lettering it is caused because the die moved during the strike making it a machined doubled coin.

I don't know where to find that, but this should help. It has clear pictures of MD and hub doubling.

Yes! Thank you Amida. This should help Khasil. Notice the level of the Doubling and how Machine Doubling is Flat and shelf like. Hub Doubling is the same height and thickness because it is in the die. That drawing combined with the understanding of how a coin is minted made me understand the difference. Happy Hunting!
