The Lynch Street Line Coin is the first item Henry Townshend obtains in the Subway World during Silent Hill 4: The Room. Shortly after entering Room 302 by a hole he found in the woman's restroom, Henry hears a ringing telephone coming from his room. When he picks it up, he hears the frantic voice of Cynthia Velasquez asking him where he went, urgently telling him that if he needs a way into the subway, she has left him some coins. After going back to the Subway World, Henry finds these coins clutched in the hands of a lifeless mannequin that eerily resembles Cynthia.
The Lynch Street Line Coin is eventually replaced on the second trip to the Subway world when Henry obtains Cynthia's Commuter Ticket.
