This is how a store clerk explained it to me when I asked the same question: They "mark" the bills with a special marker to determine if the the bill is counterfeit. If the bill is legit, the marker does not put a mark on it, but if it is counterfeit, the marker will leave a streak.
What sort of marker?
To label streak plates, use a marker or pen to write the sample name, date, and any other relevant information on the bottom of the plate. Place the label in an area that will not interfere with streaking the sample on the plate. It's important to use a permanent marker to ensure the label stays on throughout the experiment.

No, lead does not make a streak. Lead is a soft metal that leaves a gray mark when scraped against a surface, but it does not produce a streak like some minerals do.
