A lovely set of Siliquae! My favorite are # 3 and #1 (although #6 has a lot of appeal as well). I really like these little silver coins of the late roman empire, and will be looking to add one (or more) to my collection in 2017.
Looks like you had a great year! You're probably tired of people saying it, but I too like the Caracalla best. The portrait is just so fantastic!
