I will hand stamp "21 years & counting" on the aluminum piece and hearts around the year on the 2002 nickel. Nickel is the traditional gift for twenty-one years of marriage.
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.*
