Can the experts here help me with attribution on this half. I am guessing that it is O-102a. Thoughts on grade would be appreciated as well.
The obverse does not have the die break at the date.
O-102a: There is a crack at the base of date and another from top of 1 extends across bust and into stars at left.
Reverse-50 C. is 1 1/4 mm. Arrow to A is slightly less than 1 mm. A is lower and touches under the left base of M. U in UNITED broadly recut. There is a row of uniform, pointed, segments clash marked between scroll and eagle's head.
