1971-S Aluminum Lincoln Cent, AU58
Wrong Planchet/Wrong Metal Error
Rare, Briefly Circulated Example
Sold For: $31,200.00


1971-S Lincoln Cent -- Struck on an Aluminum Planchet -- AU58 NGC. 0.75 Grams. This coin weighs less than one-fourth the standard for a Lincoln cent, and it is clearly a wrong planchet/wrong metal error, struck on an unidentified planchet probably intended for a foreign coinage. At the time, the United States Mint was striking aluminum coinage for Nepal and the Philippines.

1961-D Lincoln Cent, AU58
Struck on a 1960-D Small Date Cent
Rare Year-to-Year Cent on a Cent Overstrike
Sold For: $4,320.00


1961-D Lincoln Cent -- Struck on 1960-D Small Date Cent -- AU58 PCGS. The 1960 date and mintmark are surprisingly clear, and are located near the right border of Lincoln's vest from the second strike. The second strike is rotated counterclockwise relative to the first strike. Cents struck on a struck cent are rare, since a struck cent is wider than a cent planchet, and theoretically should not fit within cent dies. Adding to collector interest, the strikes bear two different dates, and the 1960-D Small Cent is scarce, at least in comparison with the 1960-D Large Date. This is a problem-free chocolate-brown example.

Rare Flipover Broadstrike
Sold For: $4,080.00


1973-S Ike Dollar -- Multistruck, Flipover Broadstruck -- PR66 NGC. Ghosts of the reverse legend exist at the obverse margins of this unusual Flipover Broadstruck proof Ike.

This is a visually impressive 1973-S proof Mint error, untoned and fascinating in its appearance.

1963 Franklin Half Struck on a Nickel Planchet, MS66 PCGS
Rare Wrong Planchet Error
Sold For: $14,400.00


1963 Franklin Half Dollar -- Struck on 5C Planchet -- MS66 PCGS. A very rare wrong planchet striking, this piece is widely off center with the bottom of the obverse and corresponding top of the reverse almost completely on the struck coin. The result is that the date is full and in the central part of the coin. Very lightly toned with flashy, satin-like underlying mint luster and showing no mentionable abrasions.
From The L. William Libbert Collection.
