I'm a bit more pessimistic regarding grade. It appears the tops of the wings are getting involved; that's EF territory to me. This one looks like one of those "cleansed but so long ago nobody really cares" examples - it might slab, might not.
Auction is within a case of beer of my estimated retail on it. IMO, 1878-CC is a bit of an overrated issue. There are bunches on the market at any given time, and bargains can be found.
This ain't one.
