O.108a, R2. 1836/1336. One oddity to the O.108 variety is a doubling of the clasp. It is not known if this was done to test metal flow. The clasp is often weak, being directly opposite eagle's head. Or perhaps it was just fanciful design by the engraver. Interestingly this doubling appears on two different obverse dies. But the O.108 is known for a more obvious error: a 3 was mistakenly punched in the date instead of an 8. As luck would have it, the 8 overlaid the 3 almost perfectly. Only the ball from the underlying 3 shows in the 8's lower loop. Strictly speaking this isn't an overdate. No early die from another year was used. But the same could be said about many CBH's that are accepted as overdates. The a die state is attributed by the die crack at the base of the date, and another joining the right side stars.
