I have hand stamped "9 down" with a heart around the year on the 2014 penny. "Forever to go" is stamped along the bottom edge on the back aluminum piece.

Aluminum will not tarnish or change colors and has a lighter weight than stainless steel. I use real coins in all my pieces so they will tarnish over time as any coins would do.

*Due to the hand stamped nature of each piece, being stamped one-letter-at-a-time, there may be slight differences in letter placement and spacing. This is not to be considered a defect. The differences are what gives the unique character to each piece.*
