I guess we shall not keep our hopes up for a "revised" $10 note very soon.
I predict that pretty soon, we will indeed see new $10 prefixes with the new Jenkins/Dodge combo. The FEN's reported in the past few weeks are in the low 4-Million range, so we should definitely see a signature changeover in the FEN's (or BEK's) fairly soon. I also predict that the next new $10's will remain the same with the same security features as on the new $5's (which have recently been reported with the new Jenkins/Dodge combo).
So, I predict that our $10's are currently in process, with our original security features, or with some high-tech features as on the new $100's.
I will be touching base with the forum as much as I can, so I will be looking forward to the release of the next FE* or BE* prefix, hopefully soon!
