I Cant' see the image, obviously. But I have one of these, that I take with me when travelling because it's an easy way to carry pills, and make sure I don't forget to take anything while on the go. Assuming it's like mine, the container for each day has a flat lid on the top, that flips up from front to back, revealing that days pills underneath. On mine, there are two braille characters on each lid, for some reason. The first is always a braille dot 6, indicating that the next character is capitalized. Braille doesn't have uppercase and lowercase letters; capitalization is indicated by a different character before the capitalized letter. The braille dot 6 is followed by the first letter of the weekday in braille. So perhaps it's the capitalization that's throwing you off?

Getting out the container as I type this, directly above the braille letter on each lid, the letter is also in raised print. So it's probably not the same container, because it's just a single letter, not an abbreviation. Oh well. It could still be that the braille letters are capitalized, though.

edit to add: Can you give us the dots from the $1 on one or more of the braille characters?
