As I've said in other posts, I sometimes wait a while to respond to an ID-request, because I want to see what other people will say about the unidentified object before I add my observations about it.
Regarding this one:
I've been wondering for 10 days if somebody would notice that the arrows in the eagle's talons are upside down. Also, the letter A in the eagle in the eagle's shield is on a lined background. Absolutely no US MILITARY-ISSUE "eagle-button" has either of those characteristics. (I checked all the way through every one of the Albert button-book's US Army eagle-buttons to make sure my memory was correct about that.)
So, as I said previously but my post seems to have disappeared, IMO this button is not a US Military-Issue button.

> So were the tin back buttons marked with a maker's name? I'm just curious & trying to learn a thing or two on them. Thanks.
Although the great majority of tinned-iron-back buttons do not have a backmark, a few are known to exist. "Goodwin's Patent July 27 1875" (and another Goodwin's version of it saying "July 1878" instead of 1875) come to mind. There is an extraordinarily rare Confederate-made ironback North Carolina State Seal uniform button with a backmark, saying "EM Lewis & Co. Richmond VA." I should mention I've seen a few post-civil-war tinned iron back buttons with an Extra Quality or Superior Quality backmark.
