Why 3rd Party Grading?


Third-party authentication means someone other than the buyer or seller is verifying that the poster is an original and assigning it a grade. This avoids the conflict of interest that arises when the seller is verifying authenticity. The person who has a financial interest in the sale of the item should not be the person verifying its value.

This conflict of interest makes it difficult for buyers because they have to simply take the word of the seller. Even if the intentions of the seller are good, the inherent conflict of interest remains.

While MPgrading does have posters for sale on our website we do not own any of the posters that are for sale and we make no profit on the sale. Our benefit comes from making sure our dealers are successful and continue to utilize our grading and authenticating service. Every poster on this site has been graded and authenticated by MPgrading.
