The mint mark location is not correct for either of those listed ones. The location looks closer to 009. http://www.varietyvista.com/01a%20L...4SDDO009.htm
But I can tell for sure what you have on the area from the image provided? I have made an SBS yet. (Side-By-Side) I notice when you take your images, the angle shortens the height a lot. A lower angle would be better for checking SBSs.
