I'm looking forward to new $10 bills, It would be more interesting than other denominations, since we already have a less secure version, and when it comes out, we'll be able to compare the two ntoes for differences. It would be great if they made them like the new 20, 50, 100 bills. Also would love to see upgraded $5, really every country dosen't care what the face value is, security features are consistent, some countries issue hi-tech bills for notes worth less than $2 Canadian, yet include holograms and so forth. However, I watched a show on designing new US currency, and tests showed, holograms like the ones on our 100s and 20s, don't last if crumpled, the hologram's designs cannot be seen any more. Try seeing a crumpled Journey 100, you'll know what I'm talking about.
