The 1941-D Jefferson nickel is one of the more common dates with a large mintage of over 50 million coins struck for this issue. It is very common in circulated grades including up to MS63 grade. Examples in MS64 become a little harder to find but still easily available even by the rolls. In M65 condition still common but a little harder to find. In MS66 condition it becomes more difficult with many examples being graded. In MS67 condition it is very hard to come by with a few hundred examples available in this grade. In MS68 it is extremely difficult to find and PCGS has only graded one example in this grade with none being finer.
