A method of denominating commercial paper and currency comprising the steps of:

• providing a paper having indicia of commercial value;
• arranging a pair of light emitters on one side of said paper, one of said light emitters providing a clear image of said indicia and another of said light emitters providing a blurred image thereof;
• arranging a pair of light detectors on said one side in optical communication with said light emitters;
• connecting said light detectors with a logic circuit containing stored data indicative of a plurality of values;
• combining said clear and blurred images to form a resultant image;
• and
• comparing said resultant image with said stored data for determining said commercial value.

A method of verifying commercial paper and currency comprising the steps of:

• providing a paper having an embedded security thread;
• arranging a pair of light emitters on one side of said paper, one of said light emitters providing a first clear image of said security thread and another of said light emitters providing a blurred image thereof;
• arranging a pair of light detectors on an opposite side of said paper in optical communication with said light emitters;
• connecting said light detectors with a logic circuit containing stored data indicative of said security thread;
• combining said clear and blurred images to form a resultant image;
• and
• comparing said resultant image with said stored data for determining presence or absence of said security thread.
