Definitely not pesos. I bought both Bacanora de Sonora (wood box) and 300 Aņos on my last trip to Rocky Point. Both were right around $50 each. I haven't tried the Bacanora de Sonora, but the 300 Aņos was decent, but not worthy of a 50 dollar price tag.
Those 2 are the only bacanora brands I know of currently:
