Yup, you nailed it. It is just a little worn. Be it die wear or over polishing or circulation. The main thing I look at is where the top end of the G is. If it is past the upright it is the 005. If it is just short of the upright it is the 006. I have been lucky to find a total of 4 1988-P and 1988-D RDV-006. And one of the Denver ones was the discovery piece for die pair #8. So my heart has stop more than a few times with some funky looking 005's.
