What are some good ideas of things to collect?

Coins, base ball cards and stamps are the easiest to collect because bookstores usually carry books and folders to keep them in. You can collect anything that interest you. You need to consider things like how much storage space you have and how much money you have to spend and how much time you have to devote to your hobby. Some things like dolls and figurines take up a lot of space and coins and stamps can cost a lot of money. Also some things like things made of paper require special care. Many things that are collected are only valuable to the people who collect them (like refrigerator magnets). Also think about the long term. What will you still be interested in 10 years from now. Sometimes people start collections and then loose interest in them and then they are stuck with all this stuff. Think about what you like and where you see yourself in the future, then decide what you would like to take with you.
