This is a lot of vintage plastic & celluloid buttons.  All have unique decorative features, and all are good enough to use on an outfit.  They are all black.  I tried to lighten some of the photos so you could see the textures and by doing so they look a little green.  But all are black.  The largest is the size of a half-dollar down to the smallest a little more than the size of a pencil eraser.  Most are nickel size.
