If you’re looking for cash quick, this could be your place. If you’re looking for someone actually interested in coins or their history, look somewhere else. Only one small step up from a pawn shop— Nicholas Bellomy, Feb 2026
After spending some time researching businesses in the area and reading reviews, I chose M.A. Storck to have some gold and silver jewelry evaluated with the interest of selling and I was not disappointed. The owner, Sullivan, was courteous, knowledgeable, forthright and very transparent about his assessment of the value of the items I brought in and what he was interested in buying. I expressed interest in his trade and he took the time to walk me through his process of testing metals, the history of his business and the math he used to calculate his offer. No rush, no pressure, no lowballing, totally fair in my opinion (it's a very small operation and I visited during nice weather so it wasn't very busy - keep that in mind come tourist season in Freeport - be patient). More than money, I value time, history, a good conversation, and a genuine learning experience. I got all of those at M.A. Storck. Thanks Sullivan. Looking forward to my next visit.— Michael Bensur, Apr 2025
Fantastic experience when visiting from out of state. Sullivan was friendly and helped me pick out the perfect souvenir coin at a fantastic price. Highly recommend this business.— Justin Smith, Oct 2025
I stopped in the first time and was treated very kindly and with patience as I asked many questions. I returned with coins and I was able to get a very thorough examination and walk thru on what I had. Sullivan is knowledgeable and his service is exceptional.— noel hebert, Dec 2025
I had an excellent experience selling my coins here! Sullivan was knowledgeable, professional, personable, and took the time to explain the value of each piece. I really appreciated the honesty and transparency throughout the process. I felt confident I was getting a fair price. If you’re looking for someone trustworthy and reliable to buy your coins, I highly recommend them! Thank you Sullivan!— Nora Piper, Sep 2025
I went in to Sullivan’s shop las week with many many pounds of coins that I inherited from my grandfather. It was late in the day and I am very new to coins. I am curious and have been excited about the prospect of learning about these coins and about my grandfather as a result. Sullivan could sense this, and spent over an hour and a half going through every coin with me, and even stayed open late to get the job done well. I learned about silver quality, notable years for certain coins, and more. He was so patient and kind and thorough. I didn’t have any high value coins, but I do have a new hobby and awesome resource for once the weather turns colder. I would recommend Sullivan and his shop to anyone looking to learn about/sell/buy coins or silver. I will be back soon! Thank you, Sullivan!— Maggie Johnson, Sep 2025
