Thank you, muddler - I thought the same on the similarity. This was a tough coin to find in a nice grade and strike.
The 7070 is kind of hit and miss on what they do/do not include. It is mostly there, but there are a few notable exceptions as you point out. I've debated putting an 1873 in my half dollar with motto slot to cover both arrows and motto - but I've got to find one first! Not crazy about the 1875 I have in there now - the dark toning is a negative.
