Of course A.C. never had silver dollar slot machines as all .999 fine silver coinage ended in 1964. When Resorts first opened in 1978, they used large size tokens that were the same size as the Eisenhower dollar.

When Boardwalk Regency opened a year later and the smaller size Susan B. Anthony dollar was being issued by the US Government, Boardwalk Regency tooled up their dollar machines with a token that was the same size as the SBA dollar... which never became popular.
