Time Lord in Gallifreyan
Size of plain disks are 1 1/2" in diameter. I have stock in various metals: Nickel, Brass and Copper.
When you purchase you will receive your saying on whatever metal I have available.
The metal will slowly tarnish as time goes by giving it an incredible patina. If you don't want the metal to tarnish, you can spray it with a clear coating of polyurethane.
