1861 Gold US Quarter Eagle

This is an 1861 US gold Quarter Eagle. It spent its life inside a locket. I know nothing about grading, but this coin is in very nice condition with the only defect visible to me being a small nick on the date as is visible in the photos. I believe that this is a type I coin -- the differences being the size of the arrow heads on the obverse and the spread of the eagle's talons. Please ask me questions if I've omitted anything. Thanks for looking.
