Wanted: 1964-D Kennedy Half Dollar MS67 PCGS Cert # 21907519
I am looking for owner of/to purchase 1964-D Kennedy Half Dollar MS67 PCGS Cert # 21907519. Originally obtained when building a 1964 Mint Set Regrettably, i sold this coin in June 2019 via Heritage. Now working on a Half Dollar Type Set, I would very much like to repurchase this coin from its' current owner. If any collectors here own this coin and would be interested in selling or can offer assistance in identifying its' present owner, your help would be greatly appreciated!
