- Condition: The overall condition of the poster, including whether it has any tears, creases, or stains, will impact its value.
- Rarite: The rarer the poster, the more valuable it will be. Limited-edition or promotional posters are typically more valuable than widely distributed posters.
- Authentication: If the poster has been authenticated by a reputable source, such as a third-party authentication company, its value will be higher.
- Market Demand: The demand for Green Day autographed posters among collectors and fans will also affect the value.
Generally speaking, a Green Day autographed poster can range in value from a few hundred dollars to several thousand dollars. However, some rare and highly sought-after posters can sell for even more.
