When using Mathematica to analyze financial problems, I often create graphs
in which the Y axis describes amounts of money. These are typically large
enough that Mathematica switches to scientific notation (that is, 2.7x10^8
rather than $270,000,000). I can force the latter with a custom Ticks
function (Table[{i,"$" <> ToString[NumberForm[i, DigitBlock -> 3,
ExponentFunction -> (Null &)], etc.) but this becomes inelegant when it's
buried inside a Manipulate call and the range and spacing of the ticks are
changing. Is there some straightforward way to change the formatting of
these tick numbers?

Thanks,

Michael Stern
