Like comic books and trading cards, a lucrative collectibles market has developed around vintage concert posters. CGC, the world’s leading comic book certification and grading company since 1999, employs a 10-point grading scale for concert posters that is based on the industry standard the company established for comics, magazines and other collectibles. CGC-graded concert posters are inspected by at least two grading professionals to verify its authenticity and then sealed in tamper-evident holders of a heavy gauge archival plastic. The fully transparent front and back allow complete viewing of the poster and protect from any improper handling or soiling.

CGC currently accepts concert posters from some of the most highly coveted vintage poster series: Bill Graham, Bill Graham Presents, Family Dog, Grande Ballroom, Neon Rose, Art of Rock, New Fillmore Series and Moonalice. Posters must fit within a space 22.5 inches wide by 29.5 inches high.
