В конце романа "11/22/63", когда Джейк попадает в реальность, где Кеннеди жив, подростки требуют у Гарри новобаксы, также упоминаются старобаксы. Эта валюта присутствовала в "Бегущем человеке".

The clouds rifted. The moon peeked through. By its chancy light I saw an old man in a wheelchair. He was halfway across one of the streets intersecting Main—Goddard, if the name hadn’t changed. One of his wheels had gotten stuck in a pothole, causing the chair to cant drunkenly to the left. The boys were crossing toward him. The kid who had told me to fuck off was holding a slingshot with a good-sized rock in it. That explained the bonk and the spang.
