"A Coin Exchange" first opened its doors to the public in October of 1997. It began as a joint effort between Mark and Jonathon who have over 70 years of combined experience in the field of rare coins and precious metals. They decided that what the industry lacked was a retail store where people could expect honest, straightforward and courteous service along with competitive prices. We continue every day to remember this basic business model.
