It is a button. The side with the writing is the back, and included in the backmark (as it's called) I can read Extra / Superfine on the inner text and Waterbury Co (maybe Conn) on the bottom outer text. And Benedict & Burnham on the top.
-- like this one: http://www.shilohrelics.com/cgi-bin/Display_Item.asp?115161
And this would date 1834-1843
I can't tell if there was or wasn't something on the front.
