Butcher covers from the first known documented sale in 1974 to the most recent sales in 2000, plus projections to the year 2006. It was collector Jerry Osborne's auction catalog in 1974 that listed, for the first time, a near perfect copy of a first state sealed mono Butcher cover. The chart values have been calculated throughout the years based on actual sales from a variety of collectors and dealers, and include averaged sales of many different copies with slight grade and pedigree differences. Note that the values usually represent high grade or pedigree copies. Some sealed albums may have wear, bent corners, torn shrink wrap, etc.
Value can vary significantly based on condition, even though sealed.
Livingston copies always bring a premium.
