I purchased some coins from this store for my husband's birthday. I know nothing about coins and have had disastrous results because so many coin dealers will inflate the price if they know you do not know what the true value is. I was in the shop for quite a long time, and the employee was very patient with me. My husband liked the coins, and said that I was charged a fair price. They are honest with their grading of the coins as well. I know they have auctions at their Naperville location, but I have never been there.
