Wheels....
In my opinion.... I would probably go for a note that has a value of $1000 rather than a $1000 note..... Like an UNC devils face $50...(may need to get a deal on that a bit but all the same..)
But that is all personal preference and what each person finds desirable....
example.... I've always really like the multi-coloured notes.... and have been collecting them all my life...only recently with Dean's posts was I turned on to the fun I can have with pennies... now i love it... and learning a whole lot about coins in general.... I've started looking at other coins and may get into that a bit too...
But right now.. I'm really just craving some rabbit soup!!
