Coins and banknotes are like special pieces of paper or metal that people used in the past to buy things. Poland is a country in Europe, and they also had their special coins and banknotes in the olden days.
Let's start with coins. Coins are made of shiny metal, like a little sandwich with two sides. In Poland, they had different coins for different amounts of money. Some coins were very small and worth just a little, like a small snack. Others were bigger and worth more, like a bigger toy. The coins had pictures on them, to make them special. Some coins had the pictures of important Polish people or symbols, like the national eagle or a famous castle.
Now, let's talk about banknotes. Banknotes are like special pieces of paper that are worth money. Poland had different banknotes for different amounts of money too. Just like in a game, the banknotes had numbers written on them to show how much they were worth. Banknotes were bigger than coins, like a big piece of paper. They also had pictures on them, just like coins. These pictures showed important Polish places, like palaces, buildings, or even famous people from history.
People used these coins and banknotes a long time ago to buy food, clothes, or toys. They would go to a special place called a store and give these coins or banknotes to the person behind the counter. The person would then give them things like candy, clothes, or toys in exchange. It was like a special language using money to get the things people wanted.
But the coins and banknotes of the past are not used anymore. Nowadays, people use different coins and banknotes that have new pictures and designs on them. But the old coins and banknotes of Poland are very valuable and special to collectors who love history. They can look at them, study them, and sometimes even trade or sell them to other collectors to keep history alive.
