The uniformity of colour suggests they have been dipped or cleaned in some way, and the absence of fine veil detail says there isn't a single uncirculated coin amongst them. Yet again, the number of genuinely uncirculated coins is a very small percentage of the total available. Yes, they should be desirable simply on rarity alone, but less than uncirculated deserve better acceptance than is currently the fashion. Historically people used to collect in all grades, but grade inflation has helped many people to assume that only high grade is good, and that low grade is the new high grade.
