I can't find any listings in Breen or by googeling a 1978 no fg half. I can find several others but not this one. Does anyone have any info. Thanks Len
Missing initials can either be from an overpolished dies or just a filled die (and in the case of a filled die they can come and go.) and they can happen in any year. Some years are known for them but they can easily exist on other years and no one knows or cares about them. Unfortunately that doesn't mean they are worth anything.
