So-Called Dollars


Book Description

When So-Called Dollars was published it was the first, and it is still the only book to deal comprehensively with its subject matter. The book begins with the legendary Erie Canal Completion issues of 1826 and proceeds to catalog 135 years of the Golden Age of American history, all the way up to 1961. Although there have been many propositions for reviving the book over the years, none were more than theoretical musings until two collectors, Tom Hoffman of Crystal Lake, IL and Jonathan Brecher of Cambridge, MA set the process in motion. They have been joined by two others, Dave Hayes and John Dean, to produce a remarkable new edition, of the sort that can only be the product of dedicated hobbyists who love their subject and see it as their obligation to share with others the knowledge gained from years of collecting. While the second edition holds true to the original in basic style and in substance, prices have skyrocketed and it offers much that is new. There are many more illustrations than in the first edition. In fact, virtually every type is now represented by a photograph. More historical information for the issues is presented in the text, which has been further expanded with additional listings of both previously unknown metal varieties and totally new items. The size of each item is now given in mm rather than in 16ths of an inch as in the 1963 edition. Each issue has been assigned a rarity rating of from R-1, indicating more than 5,000 known, to R-10, meaning unique. In addition, a loose-leaf price guide included in each book at no additional charge. The index has been expanded to include references to more subjects and places. Finally, there is a section of color plates. The Hibler & Kappen book remains the standard reference work on the subject with its HK numbers an instantly recognizable means of cataloging and identification.




An Engine, Not a Camera


Book Description

In An Engine, Not a Camera, Donald MacKenzie argues that the emergence of modern economic theories of finance affected financial markets in fundamental ways. These new, Nobel Prize-winning theories, based on elegant mathematical models of markets, were not simply external analyses but intrinsic parts of economic processes. Paraphrasing Milton Friedman, MacKenzie says that economic models are an engine of inquiry rather than a camera to reproduce empirical facts. More than that, the emergence of an authoritative theory of financial markets altered those markets fundamentally. For example, in 1970, there was almost no trading in financial derivatives such as "futures." By June of 2004, derivatives contracts totaling $273 trillion were outstanding worldwide. MacKenzie suggests that this growth could never have happened without the development of theories that gave derivatives legitimacy and explained their complexities. MacKenzie examines the role played by finance theory in the two most serious crises to hit the world's financial markets in recent years: the stock market crash of 1987 and the market turmoil that engulfed the hedge fund Long-Term Capital Management in 1998. He also looks at finance theory that is somewhat beyond the mainstream—chaos theorist Benoit Mandelbrot's model of "wild" randomness. MacKenzie's pioneering work in the social studies of finance will interest anyone who wants to understand how America's financial markets have grown into their current form.
