The Prisoner Coin is a puzzle item found in Room 109 on the first floor of the Blue Creek Apartments in Silent Hill 2. After the cutscene with Angela Orosco and obtaining her knife, James Sunderland can find the coin on the nearby nightstand.
The coin is one of three that must be used to solve the Coin Puzzle in Room 105 of the Blue Creek Apartments. The puzzle yields a room key when solved, which can be used to enter Room 209 on the second floor.
The coin may represent Angela, as upon closer investigation in his inventory James will comment, "This prisoner looks like a woman." The woman on the coin appears blindfolded and has a hairstyle similar to Angela's. Also, the coin is found in the confined room where James finds Angela pondering suicide. Angela is also known for her childish speaking ("Mama") and abusive childhood, and just outside the room children's toys, such as a stuffed bear, can be found and examined by James.
