4 Revolutionary War Buttons, coat size, all original, all are complete

Description

These do not match but they are all about the same size and they all have unbroken loops on the back.  They are all original and they are made  of tombac,  a common metal during the colonial era.  Some or all may have been dug, but they are all in good and usable condition..  I am selling my long-time collections.  I combine shipping on multiple items.
