thanks for writing in with the following hallmark question: "I recently received a ring that was my Grandfather's, after he died. There are two hallmarks. One is 10k (I am assuming for the quality of the Gold). The second is a circle with a T inside. Would love to get help identifying what that means!"
John, the maker's mark look very similar to Eugene S. Toner Co. (probably Distributors, New York, NY, USA) - ca 1902 - 1914 but mostly found on Sterling Silver.
