15. Erasers
Remember going to the school store as a kid and picking up a novelty eraser? Those were the days. This collection appears on a website called Joe Wood Worker, where he shows his eraser collection that currently totals 2,900. Joe spent 34 years collecting these erasers, starting from a school trip he took to the Baltimore Aquarium when he was a boy. This collection could potentially break a Guinness World Record, but Joe would have to apply for it first.
