HISTORY AND COMMENTARY
While plate blocks of the 30¢ Columbian are more available compared to the dollar denominations, prime top positions without reduced selvage are very scarce. Of the handful of top plate blocks located in Power Search, only one (ex "MLG" collection) had selvage that was not reduced or narrow.
