Task: Question Generation
Input (English): Passage: Several of the most expensive items of sports memorabilia and baseball memorabilia ever sold at auction are associated with Ruth. As of November 2016, the most expensive piece of sports memorabilia ever sold is Ruths 1920 Yankees jersey, which sold for $4,415,658 in 2012. The baseball bat with which he hit the first home run at Yankee Stadium is in The Guinness Book of World Records as the most expensive baseball bat sold at auction, having fetched $1,265,000 on December 2, 2004. A hat of Ruths from the 1934 season set a record for a baseball cap when David Wells sold it at auction for $537,278 in 2012. In 2017, Charlie Sheen sold Ruths 1927 World Series ring for $2,093,927 at auction. It easily broke the record for a championship ring previously set when Julius Ervings 1974 ABA Playoffs ring sold for $460,741 in 2011.
Output (English): How many more dollars did the most expensive piece sell than Charlie Sheen's ring and Julius Erving's ring combined? ?
