There are two large sizes of the Monte Santo Olive Oil bottles as well as a sample size. So uh, three sizes total that I am aware of. The monogram stands for Coffin-Redington Company. There are several different types of Coffin-Redington bottles, mostly grocery/food containers. I've got a small box of different local olive oil bottles - all with embossing. I don't know if anyone out here in California collects olive oils, so price/value is a tough one to estimate.
