Ron Guth: The 1943-P Double Die Obverse "Nickel" is one of the most popular varieties of the Jefferson series. Though it is scarce as a variety, high grade examples seem to be the norm. As of April 2011, PCGS has certified 183 examples, mostly in the MS-65 and MS-66 grades. Of the 183 examples, 29 have full steps. The finest examples graded by PCGS are two MS-67FS's.
This variety is not an arms-length one, so it remains possible to cherry-pick one by examining all 1943-P Nickels. The doubling is most evident on the date and LIBERTY. Jefferson's eye shows clear doubling in the form of extra lines that jut out from in front of the eye.
