Value for a genuine Egyptian Scrab?

I have a New Kingdom (1479-1070 B.C.) Egyptian Scarab. Tuthmosis III, Steatite, blue-green glaze, faded to brown measuring 14x11 mm. Seated falcon god on left with Mer sign over his head. In front of him is " The good God, Lord of the Two Lands". Below that is cartouche of Tuthmosis. It is unusual, and finely executed. I have detailed pictures available for viewing. Note: This is not a fake. I am well aware of the fakes on the market. Any information is greatly appreciated.
