Did you note the flow lines on the die on the obverse of you coin? (below the '5' on the date) That is a sign of extreme die wear. So what you are on the motto is another aspect of heavy die wear. It is called die wear. This happens as the die get old from use. The dies pushing the metal of the planchet, causes the dies to wear out. This is not a fast process, but a slow process. Die flow starts to show on dies as they reach the LDS (Late Die State) Get even stronger when the dies move into the VLDS (Very Late Die State). The coins show the story. But the better looking coins are from the EDS (Early Die State) But just a few of them happen before the die starts to age. Note a chart comprised on the number of coins per die states:

Sometimes you can see lines on the tops of the devices. Most of the time it is coin contact that alters them. But on some proof coin (nickel) you can see them from the striking process:

That is probably from die wear, but proof coins are only used for 6,000 strikes.
On business strike coins you can see the lines from incuse devices that the MD slides a bit before the strike. This is call Striation lines:

On raised devices we see these also:

These lines are very fine. It is caused by the roughness of the metal slid. If you took some soft butter, you could take a pairing knife and lightly skim it on the top of the butter. This will leave a copy of the edge of the knife on the butter. (probably used in forensic tests)

No, your coin shows MD and die wear.

Centavo69, I think you probably understand that everything on a die comes out opposite on a coin. Everything raised on a die comes out recessed on a coin. Everything recessed on a die comes out raised on a coin. I think you understand all that, it's pretty basic.
If you take that one step farther, you will realize wear on a die adds recess to a die. The wear recess on a die becomes raised on a coin. It's often mistakenly thought to be doubling. There are several ways to tell "die wear doubling" from a Doubled Die. The "die wear doubling" on a coin is usually sloppier and raised very little when compared to the Doubled Die.
Machine Doubling (MD) AKA Strike Doubling, is also often mistaken to be a Doubled Die. It is caused by unintentional extra movement of the die at the time of the strike. The die first strikes the coin leaving perfect devices, then unintentionally moves and alters the devices. Depending on the direction of the unintentional movement the altered devices can be smashed flat at their edges (usually with striation lines) or the devices can come out with as little as lines in them from just a "kiss movement". This phony "doubling" can be differentiated from the Doubled Die by being not as tall and by being part of the original device. The Doubled Die is not part of the original device, it is alongside it. Understand that, and you will understand Reduced Devices. Take the time to understand these three paragraphs, I think they should help you tremendously.

I am not always correct so please understand what I say is my opinion.

Centavo, what I do is go to doubleddie.com,find the kind of coin you have, click that then the year will come up. If you donít see the year of youíre coin itís not a ddo/ddr (most likely). Also if you donít find the exact coin youíre holding on the list of dd coins itís not one either. Unless itís a new find and theyíre arenít a lot of those out there. There will be markers on youíre coin that match the one you see there if it is a genuine dd.
