Well it looks like yours had stars at one point. I think I see little dimples on yours which are probably worn down stars. So could be this 👉 gilt Navy button
Not sure if this is true but it’s from the above Tnet link “I think it is post cw. Eagles head is facing right. Pre cw eagle is facing left.”
Top picture is from that Tnet link, bottom right is from the second US Militaria link, bottom left is a bunch of random navy buttons from Etsy with your design.
