Defacement of currency is a violation of Title 18, Section 333 of the United States Code.

It’s not inherently illegal to write on money. It’s only a crime to deface money “with intent to render such item(s) unfit to be reissued” which is admittedly kind of vague. Basically if you write on it in a way that would make it unusable it’s a crime.

US dollar notes are legal tender, even if someone writes on it or stamps a message on it. It’s good, as long as you don’t cut off too much of it, or tear it in pieces. Neither action is a crime… you can either destroy or deface US currency, but if it’s whole and recognizable, it’s good.

According to Google’s built-in dictionary, deface means “spoil the surface or appearance of (something), e.g., by drawing or writing on it; mar or disfigure.” Thus, it appears that writing on money is punishable by up to six months and/or an unspecified fine (a misdemeanor).

Yes, It’s Legal! Many people assume that it’s illegal to stamp or write on paper currency, but they’re wrong! You CANNOT burn, shred, or destroy currency, rendering it unfit for circulation. You CANNOT advertise a business on paper currency.

Unless there is an increase in economic activity commensurate with the amount of money that is created, printing money to pay off the debt would make inflation worse. This would be, as the saying goes, “too much money chasing too few goods.”

The first reason that comes to mind is printing counterfeit currency is illegal, and it definitely is. It is a pattern of small circles printed on almost all modern currency notes in circulation, commonly called the Eurion constellation.

So yes, there can be a short-lived stimulative effect of printing money. Bottom line is, no government can print money to get out of a recession or downturn. The deeper reason for this is that money is really a facilitator of exchange between people, a middleman in a trade.

Because printing money doesn’t do anything to increase the money supply. Printed paper and coin represents less than 10% of the actual cash in circulation. More than 90% of the cash in circulation is held inside of bank account ledgers, investments and other things that hold value.

Producing or using counterfeit money is a form of fraud or forgery, and is illegal. Another form of counterfeiting is the production of documents by legitimate printers in response to fraudulent instructions.

Because counterfeiting is highly illegal, a photocopier will refuse to copy a bill, and Photoshop will reject the image. The pattern depicted in blue dots in the screengrab above is called the EURion Constellation, and was a security measure found in multiple international currencies.

One estimate detailed that more than 75% of the nearly $600 billion in $100 bills circulates outside of the U.S. Due to its popularity, the American $100 bill is one of the most counterfeited currencies, but also one of the most difficult to fake.

Digital vending machines are so able to read and accept money with the help of a magnetic head that reads the ink on a dollar bill. Good quality fake bills can closely resemble the real ones and the electronic sensors on slot machines may not be able to catch the difference. …

Under federal law, the use or attempted use of counterfeit currency is illegal if the person has the intent to defraud the recipient. A conviction for the offense carries up to 20 years in prison and a fine.

Overall, casinos are a very trustworthy and are safe places for money. They take great precautions, that you don’t hardly ever have to worry about getting fake money from them. Casinos can’t afford to have someone bring fake money in, therefore they take all the proper precautions.

Al Fester of the U.S. Secret Service said, “The Secret Service does not recommend the marker pen.” The pen reacts to starch contained in most paper sold around the world. Real U.S. currency paper does not contain starch. So if the bill is real, the ink turns yellow.
