I have hand stamped a heart around the year on the penny and "Happy 21st" on the back aluminum piece. Be sure to check out my other items to see what I have to offer.
Aluminum will not tarnish or change colors and has a lighter weight than stainless steel.
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.
