Colorized Limited Edition 2-Sided Genuine Legal Tender $100 US Bill. Amazingly, artists developed innovative technology to increase the collectibility of these uncirculated notes. When applied to Benjamin Franklin's face (front side) and Independence Hall (back side), the vibrant colors of the original art are restored, bringing these beautiful works of art to life. These pristine, enhanced new design $100 bills make an excellent currency collectible and unique present. Due to the time-consuming colorization procedure, only a small number of these bills are now available. These are by far the nicest and most immaculate banknotes I've seen.
