When I started looking for errors, I knew nothing of machine doubling. The more I learned about the minting process, the easier it was to spot machine doubling vs. doubled dies. Even today, I can make a mistake in identification.
Based on your images, which are very poor in detail, I see signs of machine doubling. It could easily be the result of the bad lighting and the handheld camera or cellphone you are using.
If you are going to be taking a lot of close up images, please invest in any good device to keep your camera immobile. A good macro setting or lens would also be a plus. Lastly, experiment with lighting. Good lighting, combined with the above suggestions can make details pop.
