Rinker, editor of Warman's Antiques and Their Prices and Warman's Americana and Collectibles , here demonstrates how to establish an investment program. He expands more on the antiques and collectibles market than does A.J. Koch ( How To Get the Most Profit from Your Collectibles , LJ 4/1/82). Establishing a portfolio is the primary concern before preparation of any sale. Like Richard Rush ( Selling Collectibles for Profit and Capital Gain , LJ 1/1/82), Rinker discusses pros and cons of auction, shop, and dealer. Koch and Rush address more specifically the kinds of collectibles, associations, and bibliographies. All three titles are important; Rinker's may be the most business minded. Recommended.
