In the late medieval and early Renaissance period, especially in Italy, "wedding tokens" were frequently made from bronze or pewter, and distributed as favors for those attending a wedding celebration. Some of these were actually crafted into pendants.  

We have done this one out of nickel. It features a man and a woman gazing at one another, a clear pair. We've left the back plain, so we can, for a small extra fee, custom engrave words of your choice on the back. 

These make a perfect anniversary, wedding or engagement gift!
