These are for the NCR money as seen in New Vegas. They have been cleaned up and heavily modified to appear more like bank notes that have not been heavily used.
Each stack contains six (6) of each bill ($5, $20 and $100).
Every bill has a unique serial number and is printed on sturdy card stock (durable) with a laser printer (ink will not run).
What you see in the pic is what you will get, 18 bills in total with a custom NCR Republic Reserve bank wrap.
They are not "weather" so you can decide if you want clean looking bills or to age and weather them yourself.
