Double Struck

Double Struck When a blank planchet is struck by the dies, the normal procedure is for the feeders to eject the struck coin out of the collar and into a chute. If there is a malfunction and the struck coin isn't ejected, it may receive a second or third strike by the dies. A multiple struck coin can happen in many ways and have many combinations of errors.

A condition that results when a coin is not ejected from the dies and is struck a second time. Such a coin is said to be double-struck. Triple-struck coins and other multiple strikings also are known. Proofs are usually double-struck on purpose in order to sharpen their details; this is sometimes visible under magnification.

1882-CC $1 GSA Morgan Dollar--Double Struck, 5% Off Center--MS62 NGC. Sold for $29.900. VAM-2. This Carson City dollar was struck twice by the dies. The first strike was approximately 5% off center toward 6 o'clock, with the denticles beneath the date absent from the flan. The second strike was presumably a partial collar strike, although the edge is not available for inspection, as the coin remains housed within its black plastic GSA holder of issue. The piece did not eject after its first impression, and no additional planchet entered the coinage chamber. The second strike was well centered between the dies, and there is no rotation relative to the first strike, although the designs are several degrees north of the initial impression. Portions of the date from the first strike are obvious within the denticles beneath the date for the second strike. Diagnostic of a double strike, the eagle's wings and Liberty's profile have a distorted appearance and broad, flat outlines. These flat outlines are design portions from the first strike that were flattened by the second strike. Liberty has two ear lobes, and LIBERTY has a wider shift than seen on any 1878 VAM. Lightly toned and fully lustrous, and these two favorable attributes led to the piece's appearance in the GSA sales of the 1970s. Although slightly out of round due to broad rim at 6 o'clock, the piece nonetheless fits easily within the standard black plastic GSA holder. One can only speculate how the fortunate numismatist recipient of the piece reacted to it upon first sight. The coin has considerable eye appeal given its MS62 grade, since the reverse field is well preserved, and the obverse has only minor grazes on the lower left obverse field and on Liberty's cheek and neck. The only abrasion worthy of singular mention is a thin and mostly vertical scuff on the eagle's body. An NGC Photo Proof accompanies the lot, as does the GSA certificate and box of issue. The cataloger is unaware of another offering of an off-center, double struck GSA dollar, and the present piece would be a standout contribution to a specialized Carson City holding. (#669900)
