Grep - Superscription the the first $ sign or the ¢ sign and the last 2 digits

Hello.

Someone before me created an expression in InDesign CS4 that will superscript the $ sign, the ¢ sign and the last 2 digits but when I converted to CS6 it stopped working. I work on grocery ads and I use this a lot when adding prices to an item, and the grep expression saves me a great deal of time. Anyone out there having the same issues, and or can lend me a helping hand on creating a new one in CS6.
