Navy button id help

[Mainedigger]

Found this button in a plowed field of an old farm . Can't really see it but there is an anchor grasped in the eagles right talon. The button is also puffed out and shown with a Merc for size comparison. Any idea of the age/timeframe of this button?? Thanks.

Can't see an anchor. Looks like a mid 19th century U.S. Army General Staff cuff button. There are quite a few varieties: different styles of shields, stars, etc. Here's an example:

PBK....thanks for that, however I dont believe it is an Army button, there is definitely an anchor in the eagles right talon, my photography skills lack and can;t get a good shot showing the anchor, but it is clearly there so I would say it is more than likely Navy not Army issue.
