If time frame is not in the equation, what is the difference between Economy, Standard, and Express in the grading process? I have submissions from early Marvel to late Bronze Age. I do not know the value except by guessing (which is why I'm grading). Can an early Fantastic Four or Avengers, both number 3, be sent in as Economy or are they sent in as Standard? How do you determine the level for grading? Bronze Age comics, which are not in demand as much, are they treated the same? I am a "Newbie". Thank you.
