They do not differ. Just as in shell syntax, the { } are used to
delineate the boundaries of the variable's name. ${foobar}bas
evaluates to "bas" if foobar is not set. Without the delineation
there might be no way to know what variable name you wanted.
number=7701
street=wyandotte
bingham=${number}$street
Thus "$bingham" is "7701wyandotte" in this silly example. For
real-world Postfixated examples, continue reading in your
documentation.
