Ecoinomics is designed to equip the reader with a full working knowledge of the global numismatic market and how it differs from country to country; it details the various factors which contribute to the value of a coin, as well as different collecting practices (such as third-party grading in the US).   Covering the range of costs and benefits involved with keeping a substantial amount of capital in coins, including performance over time, market trends, tax and insurance, Ecoinomics aims to give the reader the confidence to buy coins and to begin participating in the numismatic market.   "Robert Parkinson has written an interesting and informative guide that explains many of the most important topics in numismatics. This book will serve as a valuable resource for new and experienced collectors alike." Max Spiegel, President, Certified Collectibles Group / NGC
