Woodford,
My mother has actually lost $100 bills a couple times in her lifetime so far, so she always tells me that I would holding on to her $200s, $500s, and $1,000s if issued. And my uncle, who is not all there, told me "I would rather have five $100 bills , because if I lose one $500 bill, U'm be like "Oh Drat!" if you know what I mean.
As for WHO should be on the new $200 bill, I propose Theodore Roosevelt on the obverse, as he is the "only" president on Mount Rushmore who is not currently on a circulation coin or Federal Reserve note. Likewise I would like a picture of Mount Rushmore on the reverse of the new $200 bills.
As for the $500 and $1,000 if we did a $1,000 again (and I could really still see a use for even a $1,000 bill, but no denomination higher than that, for now) I would like to see the $500 keep William McKinley and the $1,000 keep Grover Cleveland, and I would also like to se the new $500 and $1,000 keep their same reverses, only modernized. Believe it or not, the back of the last $500 bill is my favorite design of all of the U.S. banknotes I know of. I love that oval with that hige numeral "500" with the zero in the middle that gets bigger than the 5 and other zero. And as for the $1,000 bill, the fancy text "The United States of America" and "One Thousand Dollars" would be a great design to add many security features that would be needed on such a large denomination bill. And of course, "In God We Trust" must be added in somewhere. But like I said, even with $500 bills, I'd still find it nice to also have $1,000 bills, but I am not saying $500 bills wouldn't help. They would. And so would $200 bills, just to fill in the gap even better. Of course, I would not see $1,000 bills too ofyen. Maybe around the holidays, for sure.
