1977-D Jefferson Nickel--Obverse Die Cap, Reverse Mirror Brockage--MS-66 (PCGS). This fascinating piece was struck once properly, yet failed to eject from the press. Instead it capped the obverse die, and picked up a crisp brockage from the obverse of another struck coin on its reverse. Since the brockage is complete and shows no evidence of distention, we expect that this coin freed itself from the press right after acquiring the brockage. The cap, while fairly deep at the upper obverse, does not extend all the way around that side - further evidence for a brief period adhered to the obverse die. A brilliant and beautiful Gem, and a rare and desirable major Mint error. From the George "Buddy" Byers Buckeye Collection.
