Realistic Copy Machines

As I read today, there are many purposes for holograms. One purpose is to prevent counterfeiting - money has holographic film printed into it so government officials can scan it and make sure it is real money. Another purpose is to project "copies" of items into museums while the original can still be studied by the museum staff and other people, and kept safe an a perfectly heated room as to not get damaged.
