Current notes (1976 up)are worth $2. It is 'cool' to have them in sequential order, but adds no real value. They can be obtained at most banks. A “Strap” is 100 notes so it’s worth $200, the same value if they are loose. (You used 200 loose- and I think you meant 100, as the 200 would be equal to TWO straps)

If you plan to save them then UNC and any star notes have a greater future value. (The * notes can fetch a little over face to a collector)
