1981 S proof coin sets uncirculated. We are not experts, so we don’t know if these are T1 or T2. In our untrained eye, they appear to be T1, but we will let you decide. We took a close-up of the S on each of the Kennedy half dollar coins. Please see all the photos for additional information and details. If you have any questions, please contact us and we will do our best to answer them. Domestic shipping only.
