DR-C is a stamp that was used before the star stamps as a way to grade exceptionally lovely grain by Dunhill. A one-star today would be equivalent to an A, while a two-star would be equivalent to a B (you get the idea). DR-C would (assuming it was rated similarly today) would be a three-star (which would would have set you back $2,555 in 2013). The grain is nice and the overall weight of the piece in your jaw is minuscule, at best. As stated before, coming across a Dunhill of this grade is best as a smoked estate.
