"This site is sponsored by the U.S. Mint. If they click on 'Games' and then on 'Cents of Color', children can color a quarter--either the one in use for years or one of the new commemorative quarters from the states where these have been issued. Clicking on 'Info' gives information about why the different images were chosen for each of the new state quarters. Another fun-and-challenging game, even for adults, is the Golden Dollar Puzzle, in which the user is given 3 minutes to put together a jigsaw puzzle of the golden dollar. Or, select 'Puzzle Mint' to see jigsaw puzzles of the new commemorative quarters. On the 'Cartoon' page you will see a cartoon on the 'Birth of a Coin', or you can click on 'Coins of the World' and learn how coins from different nations are sometimes like our coins but can also look very different."
