 According to reports from D-Class personnel who have had visual contact with SCP-501, it is an American $1 bill that radiates a glowing amber aura. Robotically controlled chemical analysis indicates that it is chemically identical to ordinary dollar bills. When a person views SCP-501, they are immediately overwhelmed by a desire to obtain it. Studies with D-Class personnel have shown that this desire fades after a time, but that the time increases exponentially the longer SCP-501 is viewed. Further studies have shown that those affected by SCP-501 will stop at nothing to fulfill their desire, willingly resorting to violence and even self-mutilation to achieve their goal.
