The guest stars and supporting casts were always first rate, attracting the best radio actors in both Los Angeles and New York. Pat McCracken was played by several actors – most frequently, by Larry Dobkin. Particularly noteworthy was the work of Virginia Gregg, who played many roles, including Johnny's girlfriend Betty Lewis. Harry Bartell was also a frequent guest, who did many of the Spanish dialect roles when Johnny went to a Latin American country. Other frequent guest performers were Parley Baer, Tony Barrett, John Dehner, Don Diamond, Sam Edwards, Herb Ellis, Frank Gerstle, Stacy Harris, Jack Kruschen, Forrest Lewis, Howard McNear, Marvin Miller, Jeanette Nolan, Vic Perrin, Barney Phillips, Jean Tatum, Russell Thomson, Ben Wright, and Will Wright. Vincent Price co-starred as himself in "The Price of Fame Matter" and went to Europe with Johnny on the case.
In December 1960, the show moved to New York. Robert Readick started the New York run as Dollar, but only lasted a short while. Jack Johnstone continued to write for the show and submitted scripts from California. Johnstone wrote about 350 Johnny Dollar scripts under his own name and his pen names Sam Dawson and Jonathan Bundy. Johnstone wrote the last episodes of both Yours Truly, Johnny Dollar and Suspense. He used the Bundy pen name when writing the last Suspense episode, "Devilstone".
And so, an era passed. Yours Truly, Johnny Dollar was the last continuing detective series of the Golden Age of Radio. Mandel Kramer was the last Johnny Dollar, and a close second in popularity to Bailey, when the final episode, "The Tip-Off Matter", was aired on September 30, 1962.
