Unlike today's sandblasted and chromed dies, the early dies (including the 69) were pickled in acid and then the surfaces were polished to create the mirrors. The cameo surface of the dies were very delicate, and only lasted a few strikes, with each strike becoming less frosty. The mint workers would frequently clean, and occasionally repolish the dies to extend their useful life. One of the other techniques used to extend the life of the dies was to refrost them by swabbing the recessed areas with acid.
Why the long story? I like long stories, and I like the look of the obverse of your half. The apparent uneveness of the cameo on the obverse, and the heavy cameo on the reverse indicate this one was from one of the touched up dies. Cool coin. For some reason, the 69's often exhibit that look.
Developing theory is what we are meant to do as academic researchers and it sets us apart from practitioners and consultants. Gregor

Why? Well partly because 68 DCAM was already guessed

the reverse of the halfs were deep deep cameo, and only cameo on the obverse.
