David Hall: Although there were 500,000 more 1893 Columbians struck than were struck of the 1892 Columbians, the 1893 is somewhat scarcer in all grades MS63 thru MS67. My speculation is that many of the 1893s were unsold and were placed into circulation. And indeed, the 1893s are more common in grades below MS63. The 1893 Columbians come with all types of looks. The can be frosty or occasionally semi-proof-like. They are found with all shades of toning and varying degrees of attractiveness (or ugliness as the case may be). Hold out for attractive, sharply struck specimens as they definitely exist and the wait won't be that long for the right coin.
