Experiments in Aluminum Coinage by Kevin Flynn
Many archive records were uncovered that show why the Mint was testing different metals and the results of the Mint testing with aluminum in coinage. These help us understand why some of the decisions were made. Other archive records provide details on how many patterns were struck in aluminum. For example, up to now, it was believed that only four 1868 aluminum proof sets were struck. Records clearly show that 11 sets were struck.
As all aluminum coinage, except for the 1974 aluminum cent, was struck as patterns, this book studies the production of patterns in general during this period on their production and distribution. For example, an important question is why were aluminum patterns struck for denomination for each year between 1868 and 1875. Was the Mint striking to test this alloy or simply striking patterns for sale to collectors, or striking them for Mint personal? This book explores all aspects of the Mint s experimenting with aluminum for coinage." Softcover, 58 pages.
