Lot 754
1964 MINT ERROR. Deep Die Cap. PCGS graded MS-66 Red. Quite unusual. When a blank is struck into a coin, the usual procedure is for the hammer die to strike down forcing the blank against the reverse (lower) die and the collar. The upper die then pulls back up, the lower die moves up, pushing the struck coin out of the collar, permitting ejection to occur. This is what happens when all goes well.
There is an unusual sequence which happens when the system malfunctions: when the hammer die moves back up after a strike, the struck coin sticks to the upper die. The coin adhered to the upper die is known as a die cap, or simply a cap.
With repeated strikes in that press, while the cap is stuck to that upper die, the design on the bottom of the cap will get weaker and flatter. The coin takes on the familiar cup-shape of a capped die strike (PCGS # 2890) .
Estimated Value $1,200 - 1,400.
