Eric liked to save pennies．Whenever his grandfather came to visit, he told Eric that he could have all the pennies in his pocket．Grandpa always had quite a few．
He filled a small box with pennies．Then he put some into an empty bottle．The bottle was soon full of pennies, so he started another one．
When his uncle came to visit, Uncle Alan said, “What are you going to do with all those pennies, Eric? A penny doesn’t buy much these days．Maybe you should start a collection．”
Uncle Alan took him to a store, and they bought two books．One book had little spaces for pennies made in different years．The other one told how much money a coin dealer would pay for rare pennies．Eric was amazed that a penny sometimes was worth much more than one cent．
“Let’s look through your pennies and see what you have here, ” Uncle Alan said．
They looked at the dates on the pennies and sorted them into piles by the years in which the pennies were made．Eric then chose the best one from each year to put into his collection book．He soon filled up most of the space with pennies．
One penny, however, was different．It was one Eric had found in his own backyard under a big bush．It had been there for a long, long time．He checked the date on the penny, and then looked into the book that told the value of pennies．
“Thirty dollars,” the book said! Not many pennies had been made that year, so each one was rare．
“Well, what are you going to do, Eric?” his uncle asked：“Are you going to sell it so that you can have a lot of money?”
Eric thought of all the things he could buy with that much money．Then he said, “No, I would rather keep the penny as my own．”
