how 2 tell real US dollars from counterfeit US dollars?

Answer 1

start with the paper you should see blue and red threads or hairs in it because it is printed on real cotton.

holding the bill to the light you should see a watermark in the bills (at least the new ones) showing the face of the president on the bill (except for the one dollar bill)

Every bill also has a strand that goes down the the bill vertically that says USA and the amount of what the bill is.

Answer 2

There are indeed many features that are hard to counterfeit but the one you can pay attention to is the little hair-like strings dispersed all over the bill. On a legitimate bill, you can lift this strings using a needle or fine tweezers. If you are able to do this, then the bill is good. If not, or if you can't even see the strings, it is a fake.
