The new 12-sided £1 coin will finally be here on the 28th of March.
It's the first time the pound coin has been changed in more than 30 years.
The old coin became a problem as they were easily illegally copied which meant that lots of worthless pound coins have been in circulation.
The new coin was announced in 2014 and the Royal Mint, who create the coins, said that this one will be "the most secure coin in the world" making the pound coins harder to illegally copy.
