unknown button

[xmarks73]

Went for a hunt in a woods that I have been eyeballing for a little while. Found a lot of iron/misc junk but managed to save one good one from the ground. Its a Navy Button, but I'm not sure how old. I have been locked up in a factory and school all summer, so either way, I m pretty excited about this one!

This website says 1849-1865 but I think it is 1880s, I am checking
