Civil War Pennsylvania State Seal Non Dug Cuff Button

Non dug Civil War Pa staff officers gilt brass cuff button. The front has nice detail, gilt and a nice patina. The reverse has a c.1860 depressed HORSTMANN'S NY & PHI, outside a ring of dashes, backmark. The shank is straight. It has some use wear on the rim edge and it is a high domed state seal. A tough Northern state button for your collection. There is a hair on the bottom right middle of the button I just noticed while looking at the picture. It is not a scratch. $75
