I received these shiny silver metal alphabet letter personalized name concho's about 35 years ago as a gift. I never used them. They were bought for me as a gift so I could put my name on the back of a leather belt. Leather belt is NOT included. The 4 letters spell "GINA." These letters have never tarnished, so I am NOT sure what metal they are made from. There is nothing on the back of these letters besides the screws which would help identify what metal they are made from. The person who purchased these for me as a gift said they were not "cheap" when she purchased them. I have never used silver polish cleaner on them because they have never tarnished even though they are at least 35 years old.
