Book Review 1-7 Money Travels

The book is written on money and mint. The book introduces a 50 cent coin us. The 50 cent coin goes to a bank from the mint. Next, the coin goes to a shop from the bank. After that, the coin goes to the mint from the shop. Now the 50 cent coin is very old, so the coin goes back to the mint and the coin is melted down to make new coin.
I understood that old coins go back to the mint because the coins are melted down to make new coins. I have 50 cent coin. The coin is old, so the design is not clear. I think that if I use the coin, the coin would have gone back to the mint.
