I have hand stamped “20 Years & Counting” on the aluminum layer and a heart around the year, 1998, on both coins.
I use real coins, so they will tarnish over time as any coins would do. Aluminum is a great alternative to the stainless steel pieces I offer. It 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.*
