Coneca only has one DDO listed . Description: Light spread on WE TRUST, RTY of LIBERTY, and the hair at the back of the head.
You half dollar is most likely the 69D MDO-001. http://varietyvista.com/Variety Master Listings/kennedy doubled dies 1967-1970.htm#_1969-D
OP, I'm not convinced you coin is the MDO . This is what tripling looks like on the " W & E " of WE ..
OP, here's some more tripling on the " RUST " of TRUST . I'm not seeing this, on your coin . Mines a 68-D too .
