Perfect dies. Most of the error coins in the Logan Collection are relatively self-explanatory in their method of manufacture. A simple description such as "off-center" or "double struck" provides a clear understanding of the process to produce that particular item. In the case of this partial collar error, the retaining collar (sometimes called the third die), was not in the correct position to fully restrain the expanding metal as the obverse and reverse dies squeezed this material outward. Half of the edge toward the reverse die is normally reeded while the other half toward the obverse die is slightly higher and without design. This data tells us that the obverse die was most likely in the lower or anvil position in the coining press.
