Barber Half Dollar - Date and Mintmark

This date and mintmark set is considerably more challenging than the date set alone as there are numerous difficult semi-keys (mostly O- and S-mint coins from the 1890s), and a number of issues start out at $100 or more in Good 4. Finding early mint marked dates in grades better than VG is difficult. Acquiring examples of most dates in my favorite grade, Very Fine 35, requires an outlay of over $200 per piece, even for common dates. Unlike the Barber quarters however, there are no real stoppers in this set in lower grades. These coins served many years and a well circulated piece surely shows its wear. What is unusual about the Barber halves is that the key dates in lower grades (1892-O and S) are not the keys in high grade (1904-S, 1896-O). A well-matched circulated set of halves is very tough indeed to assemble from VF to AU.
