If the die scratches on the toned photo reverse match the scratches on the non-toned reverse photo, right talon scratches to the star, you have the 64D DDO-007/RPM-001, Stage B. The Stage A has the DDO-007, RPM-001, with no scratches from the right talon to the star. The stage C has an obverse die change with no doubling anywhere on the obverse, but has the RPM-001. On your toned photo of the ST of TRUST you can see the minor DDO-007 doubling. I think your half dollar does match the CONECA listed 64D DDO-007/RPM-001, Stage B.
