There are two kinds of people who patronize coin shops: Those who know what they want but don't have it, and those who have no idea what they've got. Since 1987, Alan Kreuzer has been catering to both. He hunts for and fills specific wants for fellow numismatists, and he appraises jewelery, coins and other items that regular folks often inherit. He tests for authenticity and will make an offer to purchase gold and silver right on the spot. There are scores of coins and other items for sale in his shop, and Alan is friendly and clearly knowledgeable.
