This was an Ebay purchase of some 1968 Proof sets and in one I found this little gem. On the obverse it was struck through just under TRUST and on the edge. There are also small splits at the bottom of IN and splits and spread on all of WE TRUST and the Y of LIBERTY. On the reverse, the stars under UNITED STATES have splits and the FG is almost non existent. There's no denying the strike through, but hoping for some affirmation on the rest.
Coneca has two listed with DDO & DDR . The listing are #1 & #3 . But no image for them .. http://varietyvista.com/12 Kennedy Halves/DDOs 1968-S.htm
I checked with VV and saw both of the descriptions. I was leaning towards the MDO as it matched up more of what I saw.
IMO it’s just a crap quality proof and nothing to note except you got a half that sucks. Reed and a bewildered Sparkles the Unicorn.
