happy tuppence

I see that you have continued your story about the happy little tuppence. You have added another sentence at the end, but it is not connected to the previous sentences. You need to use a period or a semicolon to separate the sentences, and you need to start a new paragraph for the new information. Here is one possible way to rewrite your sentence in a better way:

There was a happy little coin that had the value of two pence. It was shiny and bright, and it loved the sun. It was made in a mint, where it was stamped with the queen’s face. One day, a butcher’s boy saw the happy little coin on the street. He picked it up and said, “What a fine tuppence this is!”

His grandad said to him excitedly, “That’s a lucky coin, my boy. It’s very rare to find a tuppence like that. You should keep it safe and make a wish.”

His grandad was a retired butcher. He had worked in the same shop for many years, and he knew a lot about meat and coins. He told his grandson stories about the old days, when tuppence could buy a lot of things. He was now 80 years old, and he cherished his memories and his grandson.
