Valuable Pennies

How to use Mavin to look up penny values

Maybe your grandfather left you his rare coin collection in his will. Maybe you have 20 Mason jars in the back of your closet that you’ve been filling with loose change. Or perhaps you read an article about a penny that sold at auction for $204,000, and you remembered that lucky penny you spotted on the sidewalk yesterday. Whatever it was that caught your interest, now you’re wondering that if that penny in your pocket might actually be worth more than one cent.

So now what? What exactly are you supposed to be looking for? Sure, there are lists out there of the most valuable pennies – the ones that fetch a hundred thousand dollars.
