These are flat 1 piece steel buttons with stamped steel designs. Some people think that some of the designs were used to make later pewter buttons. The patterns would be the reverse on the pewter. They measure 1 & 1/16" down to 13/16" NBS Medium. They are $5 each, so you need to email me at gbbuttons@aol.com to tell me which button you are interested in. Be sure to click on the picture to enlarge it. All in good condition with metal loop shanks. $5 EACH button.
