They aren't mines wanted a second educated opinion so I came here. Note I knew they were over grade just didn't know how much and whether worth buying/collecting often see US currency go on auction in Australia, however loads are low grade that are overpriced IKE, walkers, Kennedys and Morgans (especially these) and that aside from the fact there are fakes a plenty.
However since you guys know your
US coinage and think they are only AU, probably going to pass.
Not sure about the grading company NNC? but they grade 1965 ms-69 cameo lol and then 1964 ms-67.
