The cricket ball which was famously hit for six sixes in an over by Sir Garfield Sobers is expected to fetch 25,000 pounds at an auction. Legendary West Indian all-rounder Sobers was the first one to do so in cricketing history when he played for Nottinghamshire against Glamorgan at St Helen's in Swansea on August 31, 1968 in a first-class cricket match.
