Undergraded 1829/7 Bust Half Dollar, O-101 1829 Over 7, O-101, PCGS Gold Shield Holder AU-55. This coin should be AU-58+, as there is just the faintest evidence of wear on otherwise flawless surfaces. At arm’s length it looks full mint state, as you can see in the photo. The eye appeal is terrific. It has strong upgrade potential.
