The method of claim 1 further comprising the step of affixing a frangible container containing an older producing material therein to the surface of the paper money so that the frangible container will be broken during handling of the paper money to slowly and safety release the odor producing material where the odor producing material vaporizes over a period of time to produce a distinctive odor readily distinguishable when the paper money is stored in a relatively enclosed space.

Claim 7

The method of claim 1 further comprising the steps of affixing an audible sound generating mechanism to the surface of the paper money where the sound generating mechanism includes activation means and is constructed and arranged to generate an audible sound signal starting a prescribed period of time after actuation of said activation means to assist in locating the paper money; arranging the paper currency with other pieces of paper currency to form a packet where the sound generating mechanism is concealed within the packet; and enclosing the packet in a strap to maintain the integrity of the packet.

Claim 8

A piece of paper money having opposed surfaces and a central portrait printed on one of the surfaces; having applied to that surface opposite said portrait a first treating material arranged to form a source identifying code thereon, said first treating material being normally invisible but becoming visible under ultraviolet light; and having bonded to a portion of the central portrait a cured layer comprising a mixture of adhesive and gritty material, said cured layer defining a textured surface thereon distinguishable by feel from that of the surface of the paper money.

Claim 9

A piece of paper money having opposed surfaces and a central portrait printed on one of the surfaces; having applied to that surface opposite said portrait a first treating material arranged to form a source identifying code thereon, said first treating material being normally invisible but becoming visible under ultraviolet light; and having bonded to a portion of the central portrait a cured layer comprising a mixture of adhesive and gritty material, said cured layer defining a textured surface thereon distinguishable by feel from that of the surface of the paper money.

Claim 15

Encoded currency for use in identifying unauthorized persons having same comprising: a piece of paper currency defining a pair of opposed surfaces thereon; a first treating material applied to portions of one of said surfaces, said first treating material being normally invisible but becoming visible while ultraviolet light is shining thereon, said first treating material arranged on said surface to form a source identifying code when visible; a second treating material applied to said one of said surfaces, said second treating material also normally invisible but becoming visible while ultraviolet light is shining thereon, said second treating material being capable of rubbing off of said surface onto the skin and clothing of persons handling same to assist in identifying same; and a layer of textured material applied to portions of the other of said surfaces and defining a textured roughened surface thereon distinguishable by feel from that of said surfaces of said piece of currency.
