Detecting Counterfeits in Old Bills

I have been told that the pen is only 80% accurate and with old bills it almost never is accurate. The reason for this is the fibers used in currency has changed over the years and therefore old bills have a different fiber content.

With older bills we must rely on the feel and printing quality of the currency to determine its authenticity or place a call to the Secret Service.
