Regarding the 2 dollar bill, I went to the bank one payday, in 1959, and asked for them to get $50 in twos new money. The next week, with brand new $2s, gave them to a fellow classmate whose father owned an office supply store. His dad had them made into a note pad, cardboard backing and all. Later that month, after the senior prom, a friend and I with our dates went to The Roosevelt Hotel's Blue Room. When time to pay, I took the $2 tablet from my tux coat and began to tear off the proper number of bills. The waiter took them by the corner of the stack between his thumb and forefinger, holding at arm's length with his pinkie finger extended, to the head waiter, as if they were contagious. We watched the heated discussion between them and when resolved, our waiter brought the receipt.
That worked so well, years after active duty USAF, I cut office copy paper to bill size, and mingled them into new real $2 bills. With the guys, mostly model flyers, we would get gas and take out the stack of twos and peal off till a blank, crumple that one and throw in down saying, "That one didn't come out." We would watch while driving away, and the attendant always got on the phone holding $2 dollar bills.
