1973-S Kennedy Half Dollar -- Double Struck, Multi-Struck
PR64 Ultra Cameo NGC
$3,240.00

A spectacular proof Kennedy half dollar error showing the planchet expanded from multiple strikes out of collar. All design elements and border legends are visible, moderately centered on the planchet. This deeply reflective piece is sharply detailed and brilliant, showing strong contrast in addition to the visual interest of the error. Only a few faint hairlines prevent an even finer designation.

1977-S Jefferson Nickel -- Overstruck on a Dime
PR68 Ultra Cameo NGC
$9,300.00

Double denomination errors are rare, and all the more so from proof dies. Even more significant about the present piece is its condition. In PR68 Ultra Cameo, this 1977-S proof nickel struck on a dime displays brilliant, dramatically contrasted devices and incredible depth of mirroring in the fields. The strike is almost perfectly centered on the dime, with the reeded edge of the dime fully intact all the way around. The border legends partially run off the flan but remain readable. Elements of the dime design can be seen in the fields, including portions of the reverse legends. Eye appeal is strong merely based on technical merits alone. The spectacular nature of the double denomination error is all the more intriguing.

197?-S Clad Eisenhower Dollar -- Double Struck on Half Dollar Planchet
PR64 NGC
$11,700.00

On a few previous occasions we have been able to offer double struck Eisenhower dollars, including one in proof that featured two off-center broadstrikes. However, there are really no comparables for this piece, a partial-date proof Ike that is double struck on a clad half dollar planchet, with partial reeding around the edges. The first strike is off-center toward 3 o'clock, while the second strike is almost perfectly centered. Much of the first impression remains visible in silhouette form, especially on the obverse where President Eisenhower's head is almost fully doubled. The fields on both sides are reflective, and the devices show satiny luster. The 19 in the date are sharp, while there is a "ghost" of the 7 and the fourth digit is indiscernible. The mintmark is clear from both strikings. A few faint marks in the fields limit the numeric grade, but the singular appeal of this piece as a spectacular double struck, wrong planchet proof error surpasses the appeal of any numeric grade.
