Specimen banknote

A specimen banknote is like a pretend version of real money that is used by banks and governments to show people what real money looks like. It's kind of like a toy money that adults use to teach other adults about money.

The specimen banknote is made to look just like real money, but it usually has some differences that make it special. For example, it might have the word "SPECIMEN" or "SAMPLE" printed on it instead of a real denomination like "5 dollars" or "10 euros". It might also have special markings or colors that are different from real money.

Banks and governments use specimen banknotes to help train people who work with money, like bank tellers, cashiers, and security guards. By practicing with specimen banknotes, these people can learn how to spot fake money and make sure that only real money is being used.

So, the next time you see a piece of money that says "specimen" on it, remember that it's not for spending, but for practicing with. It's like a toy money that grown-ups use to teach other grown-ups.
