I came across these recently in a small collection I bought. I guess it never occured to me that they could be real. They looked like copies, they felt like copies and both carried the same 'serial number'. Of course, I also had the advantage of the message on the back of one of the 'notes'. Anyway, I am posting largely because I am shocked at how many people are still finding these in grandpa's stash and ask "What is this and what is it worth?" Interestingly, I find the Dr. Pepper one more collectible as a Dr. Pepper promo collectible than as currency. Enjoy...
