1881-O Morgan dollar, Choice Almost Uncirculated, from a Morgan dollar collector's book.  This specimen has minimal wear, as the photos show; in the usual places of Liberty's check, cap circumference, eagle breast feathers, and wreath leaves.  We always recommend to look hard at acquiring a high AU to forego paying the higher price of Mint State grades, if you don't think you'll look at the now-filled gap in your collection often enough to notice so much.  It's a notable addition to a collection!
