All I can tell you, is if it is agate, it ain't from Agate, CO, which is 8 miles down the old hiway. The town wasn't named for the rock agate, but for the old stockyards to load cattle cars. They lined the first car up to the 'A' gate to load. Hence 'A'gate was shortened to Agate, when the railroad changed shipping points....
The other place I look for artifacts, other than the home ranch, is east of Agate, out in the breaks....
