Mike Ponsart, Owner
Mike started in the business at the age of 9 attending coin shows with his grandfather Harry. He could barely see over the cases. While growing up, Mike attended as many shows as he could with Harry. He attended Mercyhurst College on a football scholarship and graduated with a Bachelor’s Degree. Before opening the store, Mike had branched out from doing only coins to also learn jewelry and diamonds. He is now known as one of the fairest diamond and gold buyers in Northeastern Ohio.
