Help identifying this rock.

[BobbyGman]

I'm a newbee rockhound having recently located to the Miami/Globe area in Arizona. I think what I have found is an agate. It's approx. 6" X4" X4". Any help in identifying it and it's value will be much appreciated.

Agate or Chalcedony, Chalcedony is softer than flint.

Edit: If it is Chalcedony it should fetch a decent price as cabs, looks like a hefy piece. Good Find!
