Well, one way is no two dollars have the same serial number.
Real ones have small red and blue threads embedded in the paper.
And most fake ones just don't look real. The printing is sloppy and not crisp.
And if you compare them with every little detail you might know of something is different or not.

The graph of imaginary numbers takes two axes. A part for the real part and the i part.
For the simple reason that if it were public knowledge it would be far easier for counterfeiters to duplicate real dollar bills.
There is no such thing as a $1Million dollar bill in US currency. There are some countries that have 1 Million unit bills.
zilch - without a serial number it's not moneyof course if it were a real error bill, the sky's the limit. but only to a collector.CorrectionIt's still "real money" but yes, it would be worth far more to a collector. However, the value depends among other things on which country issued the bill. It can't be from the US because there are no US bills dated 1967. Please post a new and separate question with the bill's country of origin.
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 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.
A million-dollar bill does not exist. The largest denomination bill the U.S. ever issued was a $100,000 gold certificate used to transfer money among government agencies in the pre-electronic world. A number of companies have printed fake "million-dollar bills" as jokes and novelties. None are real.
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.
in the restaurant industry they make a special magic marker that is used to test fake bills. If it turns black, it's fake. If it turns tan/brown, it's real.
