The ones I have seen from Robertsons are Ohio DOC (not CA) trade ins and they do seem to have some pretty visible wear on them. They are also DAO.
I just purchased a near new 64-5 single action on guns america from Legendary Guns for $325. I don't know if it was a DOC trade in. It was not listed as such and it seems to be in a lot better cond then the ones I have seen from Robertsons.
Don't know if this helps any, but there are some good ones out there.
