I got a batch of A-22 air-tites in today and started putting some gold sovereigns inside, and I noticed that one of them (1911) would not fit into the direct-fit airtite (22mm), it would not lie flat in the circular indentation in the plastic holder. I got a few other comparable sovereigns and they fit fine. I started thinking that the 1911 was possibly fake because all other sovereigns fit fine in the airtite holder. I took some measurements as best I could and there's nothing that really sticks out in comparison with the others I measured. Am I unnecessarily worried about a 110+ year old coin that didn't get struck with the exact right dimensions to make it fit into a plastic holder? Perhaps it's not perfectly circular or flat. If the coin in question fit in the airtite fine, I would have no reason to consider it as possibly suspect since it passes all my tests (sigma, magnet, dimension weight, ping test, etc).

Are they all the same mint? I would have thought they would all be the same more or less, but in the photos it looks like the thickness isn't equal. I think 1925 sovereigns are a bit thicker than normal.
