The date looks pretty similar to the small date here: http://www.lincolncentresource.com/smalldates/1970Ssmalldate.html
I'm confused with your photo montage. Just put the photo of the date for the coin you want our confirmation on.
Yes, that is the SD. The inner loop of the 9 points to the 7 on the SD. On the LD, it points toward the MM. Also, the mushy LIBERTY helps attribute the coin.
