Numisma (1877-1891) Added

The house organ Numisma, published by New York dealer Edouard Frossard from 1877-1891, has been added under the periodicals section.  Perhaps best known for throwing stones at the upstart Chapman brothers in the early 1880s, Frossard was never afraid of pointed editorial content, and this periodical makes for excellent reading if one wishes to acquire a sense of the coin trade during this period.
