Old quarry and old state would be about the more economical roman pisa the most.
1 Ton would be doing about 4" base under ideal soil conditions that would be fine for tha size wall but I'd like to see 6" that is close to 2 tons.
Sometimes we use sand as bedding to aid in the installation of blocks but that is minimal and also mxed with mortar.
