Arkansas Civil War or Militia Button found?

[Bagman13]

Hello Everyone....

My fiance's uncle found this Arkansas Civil War or Militia button on his property today while walking through a group of trees he had bulldozed. There was Civil War activity on/near the property. He lives in Northwest Arkansas, within 30 miles of Pea Ridge. This is the first button that he has found. Would anyone w/ a little more knowledge be able to offer any confirmation as to type or info? We pulled images of Arkansas Civil War buttons off the net, and it looks like it could be a militia button dating from right after the war? We have heard that the Arkansas buttons are rare? As always, I would be appreciatiave of any help to identify

Albert's Button book shows one that looks like this as AK 4, and lists it as circa 1875.... nice find!
