This dime seems similar to the varietyvista listing for DDO-001 (http://www.varietyvista.com/07 Roosevelt Dimes/DDO Detail Files/1967PDDO001.htm): Is it a match? Embedded is a pic of a different 1967 dime with "doubled eye" that I totally didn't accidentally take close-ups of for this post.
Sorry, IMHO your coin doesn't appear to be a match for DDO-001. It looks like what you see is more the result of Die Deterioration (a coin struck by a very worn die). Here's a photo from VarietyVista: As always, wait for the expert's opinions.
