Final hammer price was $1200 (without auction fees) (Last weekend). I stood by and watched it exceed my bid. My research indicated it was damaged (similar damaged piece NGC AU Details exists http://www.collectors-society.com/wcm/coinview.aspx?sc=24669 ).

This is lower in grade, but the top mount is exactly like the NGC AU Details specimen. Why bid on a damaged and incomplete piece?
