Do you collect smashed pennies during your vacations? I’ve had a collection of them for as long as I can remember. Because I never think far enough ahead to actually bring shiny new pennies, the smashed pennies in my collection are in various stages of tarnish, up to and including completely black. With a new project in mind, I wanted to get them as clean and pretty as possible.
It’s easy to clean your smashed pennies (or any copper, for that matter) with a paste made of vinegar, salt and flour.
If you’re not happy with your final results, it probably means your penny is high in zinc. Just use a standard pencil eraser to shine it up if that’s the case. Remember that pennies from different years have different metal compositions, so your final results will vary.
