Hamilton York Estate Buyers purchases many estate items other than diamonds, jewelry and watches. We also purchase American coin collections and other estate items including automobiles and many other items. We will purchase items for which we have expertise, or we have an associate who has professional market knowledge of the estate item. Typically rare coins are best to have certified by a professional certification laboratory such as PCGS. Over the years we have found this company to be the most reliable for grading American coins. Due to the tremendous number of counterfeit coins on the market, this is always the best choice for buying and selling rare coins.
