Parking lot dollar bill curiosity

If bullfrogs had wings…
I found it at the Raleigh show.
If the 5 and the 9 reversed places, not only would it be palindromic, but it would read the same way upside down.

Nothing to me, I spent it.

I didn’t get that right. It would have to be 66 or 99 to be a palindrome.
