A Penny for Your Lab



As many of you know a couple weeks ago the Royal Canadian Mint ceased production of the Canadian penny.  Indeed, the Mint has announced that it will actively start collecting and melting existing pennies so that they will slowly be withdrawn from circulation. So that means that the pennies that are circulating now will make for an interesting study in statistics. Over the next few years we can expect pennies to become less common in our change and one could predict that American pennies should start to become a statistically more common part of our penny collections since the production of pennies will continue in the US,

The chemistry lab here at Crandall University has had active laboratory studies of the composition and distribution of Canadian pennies as part of their model for population studies and metal chemistry. We have collected penny hoards from students over the years to build up a penny library. Indeed, one year we had a student stagger in with a dishpan full of pennies that his family had collected over the years in a hallway dresser. None of the pennies we have collected pennies in the library have an exceptional worth but the library has a good sample for each year back to the 1930's and the oldest penny ever found in a submitted penny hoard was a 1908 American penny.


You can be part of this ongoing study.The current face value of the penny gives $ 4 / kilo for a penny hoard and if you have a bucket ‘o pennies under your bed like it says in the article we would be happy to pay you $ 4/ kilo for your hoard so we can have a good random collection of penny mint years. No need to roll them ‘cause I can count them by weighing.

For the purposes of the analysis it would also be best if it were a truly random penny hoard that has not had the old pennies or the American pennies removed since they are an important part of the number analysis. No donation too small or too large we are looking to build up a reserve of random pennies that will do us a few years.
