They're U.S. Marine Corps buttons. Can't see enough details to date them, but here's a link to a couple from the Civil War. (Click on pix to enlarge.):
Great finds!! That pocket watch looks identical to one I dug awhile back. Can you make out what it says inside the back? Mine says; PERFECTION U.S.A. WTG!!! HH
Great finds RK. The Marine Corps buttons have alwasy been about the same. Can you get any backmark on either of the buttons, If you can, we may be able to date them...Congrats...Lance
