After interviewing 3 coin companies, Columbia Coin offered the best return on my aunt's coin collection, consisting mostly of pre-1965 silver alloy coins. The members of the family-owned business were very fair, informative, honest, and friendly to deal with on my visiits to their business location. Their coin displays were organized, and easy to view. They also directed us to a business that would buy sterling flatware at best price, when another told us that the flatware was worthless. They are located at SE 51st and Hawthorne...parking is convenient and uncrowded. I would not hesitate to do business with them again when the occasion arises. They are very professional and fair.
