What household item weighs 25 grams and 50 grams?

I need this for a science fair project and each item has to be one object, not a couple of objects that weigh 25 grams and 50 grams.
Update: I searched online and found that almost every answer is a group of nickels and I need a singular item. Also, I did search the house and found nothing exactly weighing that amount.
