What Do Symbols Represent in Encoded Messages?

[ƒ(x)]

Decipher the message (i have no idea what it says btw)

I would guess that the circles are vowels and the rectangles are consonants.

Technically, although most of it is clear, I believe the 2nd letter on the 4th row and 1st letter on the 5th row are ambiguous. Only 1 letter makes sense for the 2nd letter on the 4th row, so I'm going to have to guess that they mean the one from 1979–1981 (and 1999), and NOT the older or newer ones.

It asks a question, but without some context, I'm not sure there's a good answer.

Wow, there's a LOT of ambiguity in those particular letters! As of today, I count 12 possibilities, and after 2016, there ought to be 18 possibilities. They probably should have chosen a different combination to get that letter. And BTW, if you're not from the USA, you may need to do a little more research on this one.

Rectangles are bills, circles are coins. The number to the right of the figure is the number of the letter in the name of the person depicted on that piece of US currency. For example, Jefferson is depicted on the $2 bill, and E is the fifth letter in Jefferson. So the last letter on the first line is E. The letter P stands alone. Too bad Polk wasn't more charismatic.
