Eagle, Marine and ??? button dates?

[baspinall]

I found these four buttons yesterday. Trying to date them. I don't know what the other button is? The darker Eagle has fewer lines on the shield, no stars and the arrows on the right side, no back mark. The patina eagle has 24 stars about seven bars on the shield and four arrows on the left side.
Also wondering if the last pic is a ball button?

Eagle button with stars is a Federal Officer Staff Button
Eagle button with shield in center is a General Service Button
Eagle with anchor is a Marine Button

Got any backmarks you can read to date these?
Great finds by the way.
