Audio Media Grading (AMG) is the premier destination for authenticating, grading and preserving all recorded music for collectors and investors.
Third-party authentication and condition appraisal
Our goal at AMG is to increase the level of trust across our collecting community. The label created for each piece is an honest and objective representation of the item’s condition – providing collectors and investors with confidence and eliminating the frustrations of buying pieces sight unseen.
Commitment to transparency
We follow a strict set of protocols and procedures to ensure each item is inspected without bias or prejudice. Our team is trained to follow our extensive authentication and grading standards. To read more about our grading scale, see here.
We’ll take care of your grails.
Trust us – we know it can be nerve-wracking to send us your prized possessions. We’ve partnered with BCW to offer protective shipping supplies (see here). In addition, we offer comprehensive insurance coverage in the rare and unlikely event your piece is damaged. Finally, we’ve invested in a state-of-the-art, safe and secure facility to ensure your submission is safe when it’s in our hands.
World-class customer service
Customer service and communication is a fundamental ingredient of our business model. From the time your shipment arrives in our receiving department, our proprietary technology tracks your order as it makes its way through authentication, grading, fabrication, photography and finally, shipment back to you. You will always know the status of your submission and if you have any questions, our staff will provide you with prompt, courteous, and professional service – we’re always just an email away at info@audiomediagrading.com.
