Autobiography about memorable day in life for grade 6 pls help

All days are not special. But few days stand in our memories and make us feel nostalgic. One such day is my successful project in history. I collected 100 coins of 10 different countries and kept it as an exhibit in my school. There was no end for the appreciation I got from all teachers. My friends were so astonished at my collections. I shared a lot of information and it gained a good name of me in my school. That day was the most proud filled and memorable day in my life.
