Spy Cipher Decoding Medallion

Known as the first recorded encryption method, the Caesar Cipher appeared during the Gallic Wars in 58 BCE. The simple letter-shifting technique named after (you guessed it) Julius Caesar allowed him to send messages without fear of them being intercepted. Maker Seth Sterling's solid die-struck metal medallion lets you encode notes using the same 2,000-year-old technique. To establish your cipher, you'll start by dialing a number into the square window. Whatever number you choose will shift the alphabets on the inner and outer rings the designated amount of letters forward. Consider the inner disk your actual message, the outer disk the secret message. By selecting the number 1, the ring shifts ""A"" to become ""B,"" ""B"" to become ""C,"" and so on, transforming a word like hello into ifmmp. Now you're ready to send and receive encrypted letters.
