Well, that map has been laying under Carli's bed ever since, collecting, not any more quarters, only dust. That's why it was time to cash in.
Let's do the math. Math 20. Fifty states times twenty-five cents = $12.50. Time to sell this ten year investment. Sold $15, to a third grade kid studying the United States and it's Capitals. No commission fees.
For Carli, $2.50 profit on $12.50. A 20% return. For the kid, a U.S. map for his report and $12.50 in his pockets. Well done.
