Comic book values presented in the Guide are often analyzed to track market trends and comparisons to other titles. One such interesting comparison can be done with comic books introduced during the Silver Age. That period saw the premieres of titles, new heroes, and second incarnations of characters that are now among the most popular. At the Guide’s 20th anniversary in 1990, the values of top titles introduced during the Silver Age were charted.
