1978-D Nickel Is This A Doubled Die?

Need help with this one. I know you experts have to get sick of the same question over and over. I have been collecting coins for about 5 years now. Just learned about all the different error varieties to look for about 9 months to a year ago. At first every other coin I was looking at I was for sure I had found something. Quickly posted it and was quickly told the coin I had was an ordinary coin no errors, just a bunch of different kinds of Machine Doubling, Die Deterioration...etc. At first this frustrated me. The thing that helped/helps me the most is when someone takes a little extra time and a few extra key stokes to insert information as to why they think the coin is a certain type of common Machine Doubling. It only confused me when I just got "Nope" answers with no follow up. I will say that every single piece on information and or link I was given as to understanding more about the minting process, I clicked on and read, as well as did some googling of my own and more reading, looking at pics, videos...etc. I have learned a lot. I understand much more clearly what I should be looking for as well as how a Doubled die is actual produced. I understand the minting process to a certain degree. Much more so then a year ago. I am still learning though. I have never actual seen a true DD in person. I had a whole pile of coins I was planning on taking pictures of and posting for opinions. After following up on every single piece of information I was given by those who know there stuff that pile quickly disappeared and I was thinking boy how glad I was I didn't post some of those very obvious useless doubled appearing coins. I am very much grateful for all the help I have been extended by other members. I know that members are not obligated to be teachers to those just getting started. You guys all rock. Now with that out of the way. I have been debating on whether or not to post this nickel. I decided it was worth posting at least to kill my indecisiveness about this one. There is a little doubling which I think may be just Machine Doubling but what has me so curious is the extra and I mean quite a bit extra thickness in the lettering. It may be nothing and even if it turned out to be an actual DD variety the condition of the coin is not very good so I imagine no real premium would be added. This one I am really just curious about, only because of some of the pics and videos I have seen where a coin is considered a DD variety merely based on extra thickness. Any and all opinions and information are more then welcome but much appreciated. Thanks :)
