Му father is collecting coins. He has got a good collection of coins. He has got many foreign coins in his collection. There are many old coins in his collection too. My younger brother has a collection of toy cars. There are many different cars in his collection.
I am fond of collecting too. I am collecting stamps. My collection is thematic. The theme of my collection is sportsmen. I have got many stamps with different sportsmen in the pictures. I’m proud of my collection.
1) My hobby is collecting expensive cars. - I disagree. I don’t think you have got so much money.
2) The theme of my collection of gold coins is India. - It’s false. You haven’t got a collection of gold coins.
3) It’s very popular to collect metal badges. - I agree. Metal badges are rather cheap but they are beautiful.
4) In fact my collection of rubbers is very special. - I disagree. Many people collect rubbers, so your collection isn’t special, I think.
