I've already uploaded the actual pics. Also, they are all .jpg files. I don't know any cyber attack that uses .jpg files as bait.
I'm not especially good at spotting subtle differences in coin designs -- that's one reason I don't chase varieties -- but for some reason, differences in fonts (typefaces) really stand out to me. Many (nearly all?) of these fakes are manufactured in China, where they use a completely different orthography -- I do see Roman numerals interspersed with Chinese text, but reading and writing Chinese characters is very different from reading and writing words composed of Roman letters. I wonder if the numbers "look fine" to everyone involved in manufacturing these things.
Imgur is an extremely well-known image-hosting site. You may not know for sure what image you'll get, but you can be pretty confident it'll be an image, no more, no less. There have been a few exploits that actually use corrupt .jpg files to attack your computer, but staying away from certain sites could never protect you from those. I don't think there are any current attacks using that vector. (A quick Google seems to indicate the ones I remember were 2013-2014.)
You certainly picked up on the main one and was more than sufficient in this case. The U thing was just gravy. And thanks for the details about the image hosting site. I, like many others, prefer to play it safe, but is still good to know.
Sorry to say, your 2016-W is a fake American Silver Eagle (ASE). Might be .999 silver but probably not. Likely a Chinese copy. How do I know? Notice the small 'W' on the Reverse (lower-left). That's the West Point mint mark. To commemorate the ASE 30th anniversary*, every 2016-W ASE has a smooth edge inscribed with "30th ANNIVERSARY". Your 2016-W ASE has a reeded edge. So it can't be genuine. Side Note: The 2016 ASE bullion coins have a reeded edge. But no mint mark. And no edge lettering. *The edge-lettering motif on the 2016-W American Silver Eagle was authorized by Congress and signed into law by President Barack Obama on December 4, 2015: https://coinweek.com/coins/silver-e...-know-30th-anniversary-american-silver-eagle/
Sorry, it's a poor counterfeit. I'm surprised no one spotted the difference in the design on the obverse. It looks nothing like the real thing.
This. The outstretched hand is all wrong, the forward foot is way too far over the 2. And the ray under the "L" in Liberty is wrong. On a real one, there will be an indentation on the ray, like the L is pressing on it.
