Bills printed before 1990 have essentially no high-tech anticounterfeiting features. Things like watermarks, security strips, and so on weren't introduced until the series that started in that decade. About the best you can do at home would be the following:
> Look for tiny blue and red fibers embedded in the paper. These are tiny bits of very fine thread that were mixed in with the paper because they're difficult for a counterfeiter to reproduce.
> Check the teeth (points) around the Treasury Seal. They should be sharp and evenly spaced.
> Look closely at the engraving of Ben Franklin's face. Again, the lines should be sharp and clear. The image should have a certain amount of apparent depth to it.
Real
As real as a $3 dollar bill. oh wait...
The fact that you are holding it indicates it is fake. There is no such thing as a million dollar bill and one has never been printed.
You get a marker or highlighter and put a dash on the dollar bill, if the marker changes colors its fake or fold the left side of the dollar bill about 1/4 the way in. Unfold to a 130 degree angle then slowly bring the magnets close to the 1 in the top left corner and if the dollar bill moves toward the magnets, the bill is real
You Look At The Dollar I Thje Light And check If Theres An Owl
shine a one dollar bill at the sun. then take the 2 dollar bill and put it on a black or brown flat surface and shine a uv pens light on the bill if you see the back of the bill its real if you don't its fake
dip it in water. if its real it will dry and you will have no problems with it. if its fake....you'll soon know.
If u look down to your right and tilt the dollar bill it will turn green that means it real. And if it's red that means it's fake.
You can tell if an old $20 bill is fake by holding it up to a light source and looking for a security thread. If the bill is real, it will have a vertical thread embedded in the left front side. If the bill is fake, the thread will be missing.
It is a red seal that has been altered.
No. Anti-counterfeiting features on older bills are not very strong. FWIW the "extra face" is called a watermark.
The US never authorized or printed a bill of that denomination. Because there was never a real thing, such bills aren't considered counterfeits, but only novelties. It's not real money.
