Have you ever looked at the dates of the pennies in your pocket?

A group of fourth grade students at the Erving Elementary School in Erving, Massachusetts did and they discovered some very interesting information. This web site will share our students' penny information with you and give you the opportunity to conduct your own penny circulation research project. After you have conducted the experiment, you can add your data to the site and share your discoveries with others!

The Activity:

The goal of this activity is to discover which United States' one cent coins are still in circulation.

Individuals or small groups of students need to gather samples of 100 pennies that are presently in circulation around the United States. Samples should come from coins that are actually in circulation. Do not use coins that have been in long term storage. Parents and relatives are a good source for samples, piggy banks are not.

Once 100 pennies have been collected students should examine the dates on each coin and tally the number of coins minted in each year. Once all 100 dates have been recorded the data can be added to our results on this web site. We suggest that students also graph their own results.

Our students are very interested in seeing the results of other students around the United States and curious to see if your results will be similar to ours.

The Questions:

Which coins are the most common? Why?

Which coins are the most scarce? Why?

Each year billions of pennies are minted in the United States, but within a few years many of these coins seem to disappear and are no longer in circulation. What do you think happens to these coins?
