How low do you go for rare die varieties?
Let's say there's a coin that's an R6 (13-30 exist) that grades "AG details" because of scratches, cuts, light corrosion, and a sizeable punched depression on the obverse. It's offered for sale at about 50% off full retail ($35 instead of $65). Would you buy it? Or would you pass on it and look for a nicer specimen, even though it may take a year or more to find another?
