I believe that it is minor Machine Doubling! Die Deterioration doubling generally has more of a smearing effect on the Letters! Frank
It's all serious die deterioration like Mike said. i have many of these with extreme DDD. the fields look like that because the die is so worn it has an orange peel effect that;s how you tell it;s extreme die wear. JC
I grant you that the Die may have been suffering Die fatigue. However, the doubling on the Lettering is Southwest in one direction, thus it is a result of Machine Doubling. Die Deterioration doubling generally exhibits itself as doubling generally around the whole perifery of the Letters and is the heaviest along both sides of the Letter's axis. Frank
Die deterioration doubling is often present on only one side of a series of letters. For example, the motto IN GOD WE TRUST on pre-state Washington quarters often shows DDD on the left side of each letter.
