# Real-Life Treasure Hunt

You never know what’s buried right under your feet. Well, one California couple found real treasure in their backyard! When they saw a can sticking out of the ground, they dug and dug, and found eight cans filled with 1,427 gold coins! The mix of \$5 coins, \$10 coins and \$20 coins was minted (made) between 1847 and 1894, back when Americans used coins for those amounts. If you add up all those \$10s and \$20s, the coins have a total face value of almost \$28,000. But they’re worth far more than that, because the older a coin, the fewer of that coin we still have, and so the more people will pay to own that coin. One of the coins is worth over \$1 million all by itself, and all together the collection could sell for about \$10 million!

Wee ones: Which has a bigger number on it, a \$5 coin or a \$10 coin?

Little kids: If you found two \$5 coins, how much money would you have? Bonus: If the coins are worth \$10 million total and just 1 of them is worth \$1 million, how much are the others worth all together?

Big kids: If you pulled out a \$5 coin, then a \$10, then a \$20, then a \$5 again to repeat the pattern…how much would the first 6 coins be worth together? Bonus: If the couple buried the 1,427 coins again in bags, with at most 100 coins in each, at least how many bags would they need?

The sky’s the limit: If there were equal numbers of \$20s, \$10s and \$5s, how many of each would you need for the face value to add exactly to \$28,000?
