This variety shows doubling on most of the date and legends on the obverse, but it requires either familiarity with the variety or magnification to see some of the doubling. This is a variety that can still be found by examining 1970 Proof sets and the premium is high enough to make the search worthwhile. PCGS has certified approximately two dozen examples in Red, Cameo and Deep Cameo Proof. As might be expected, most examples are in high grade.
