This volume details the history of specific US coins, tokens, and medals, such as the 1792 silver half disme, the 1857 flying eagle cent, the 1876-CC twenty-cent piece
, the Erie Canal medal, the Carson City Morgan dollars, the 1794 silver dollar, and the 1933 double eagle, and collections, coin designers, Treasury officials, collectors, and other figures like Frank Gasparro, Louis E.
This, of course, was only one part of the overall problem, and similar steps need to be taken to solve the dilemma of how much money they will get if they choose a square metre of five-cent coins, or a kilogram of one-dollar coins, or a litre of twenty-cent pieces
. At the point when the totals are calculated for all of the coins, and a decision is made about which is the best alternative, the students need to exercise an important part of being a mathematician: they need to 'publish' their ideas in some manner.
