Edition of 300 this is # 113. 9 Heliotype (collotype) plates of coins. Frossard traveled to Boston to have the coins photographed and printed to the highest standards of the time by the Heliotype Printing Co. The nine plates were originally sold as a pamphlet in 1878 and then subsequently issued in an edition of 300 with text in 1879. Each of the plates is printed with a copyright of 1878. Also the first seven plates have the addition of hand inked numbers and lines to indicate which of the coins matched front and back (obverse and reverse). At this date very few numismatic publications had attempted this lavish a presentation. -- David Hanson documentation.
