intent to take advantage of the superior value of the
imitated product.
3. You can detect counterfeit money many different
ways.
Using a black light scan the bill ($5 or up) and see if
there is a strip in the bill; it should glow green.
4. You can also use a security marker to draw a line on
the bill.
The mark should stay a light brown if it is not
counterfeit.
If the bill is counterfeit the mark will turn dark
brown.
