Purchased from an antique shop in London during the bubble era. This is an imitation, similar in color to 24-karat gold, featuring the inscription "1982" and depicting Queen Elizabeth on the front and a Falkland Islands penguin on the back. The Falkland Islands are located in the South Atlantic, and a conflict between Argentina and the United Kingdom occurred in 1982 over their sovereignty. The size is 2.3mm. Please understand this before purchasing. It will be sent via Yamato Compact with tracking. P.S. There are no black spots, as shown in the third photo, which may appear to have them due to poor image quality. Thank you.
