This looks like MMS-005, the straight serif. It's hard to tell from your photos but the best way to tell is by looking at the top of the upper serif. If the top of the upper serif has a spike going up it is the straight serif, MMS-005. If the top of the upper serif has no spike and slopes down with the upper curve it is the Trumpet tail MMS-004. (also the bottom part of the lower serif should have a downward pointing spike as well for the straight serif MMS-005 mintmark, but it is hard to see that on your pictures as well)
