Cassette Tape Grading Service
Cassettes are back — not just as a nostalgic novelty, but as a serious collectible format with real secondary market value. Early hip-hop releases from Dr. Dre. Demos from Nirvana. Original Walkman-era tapes in sealed condition are fetching prices collectors wouldn't have imagined five years ago. AMG grades and authenticates cassette tapes on the same rigorous 1–10 scale as vinyl and CDs, and seals them in a case built to protect the shell, J-card, and tape for decades.
Industry-Leading Slabs
AMG's patent-pending case is the only encapsulation system purpose-built for cassettes. The sonically sealed, tamper-evident case makes any attempt to open it immediately obvious to buyers. Standard and extended-play cassettes both fit without modification.
Every Tape Has a Case
Standard cassettes, chrome tapes, and double-length — AMG cases accommodate all cassette formats. The case is designed to show the full J-card artwork through crystal-clear acrylic on all sides, so your tape is as much a display piece as it is a graded collectible. Display upright on a shelf, flat in a frame, or wall-mounted.
The Label That Tells the Story
Every AMG-graded cassette receives a custom label sealed inside the case — covering shell condition, J-card condition, tape integrity, and a unique AMG certification number. The label is permanently bonded to the case interior. It cannot be removed or replicated without breaking the tamper-resistant seal, making it the most reliable condition certificate in the cassette market.
Collectors are seeing a 6X+ price premium for AMG-graded cassettes over raw, ungraded copies at auction and on secondary markets. As the cassette market matures, graded copies will increasingly set the price ceiling for any given release.
Every Format. Every Generation.
AMG grades all cassette formats and generations. Standard Type I tapes, chrome (Type II), metal (Type IV), extended play, and sealed tapes from any era — if it's a cassette, we can grade it. Signed cassettes are graded with our standard service alongside autograph authentication.

|---|---|
| Standard Cassette | From $50 |
| Extended Play / Double Length | From $50 |
| Sealed Cassette | From $50 |
| Signed Cassette (any format) | From $50 + autograph authentication |
Cassette Grading — Common Questions
Yes — and it's growing. In 2023, cassette sales hit their highest level since the early 2000s. Limited runs from artists like Taylor Swift, Tyler the Creator, and Billie Eilish sell out immediately. Original sealed tapes from the 80s and 90s regularly sell for hundreds of dollars. A graded, certified copy commands a significant premium.
AMG grades all components: the shell condition (cracks, warping, label wear), the J-card (creases, tears, yellowing, ink fading), the tape itself (any visible damage or deformation), and overall presentation. Each element is assessed independently and contributes to the final 1–10 grade.
Yes. Sealed tapes are graded in sealed condition — we do not open them. The seal itself is assessed as part of the grading criteria.
Use a small bubble mailer or padded envelope. Wrap each cassette in a small piece of bubble wrap. If submitting multiple tapes, separate them so they can't knock against each other. Include your printed AMG packing slip. USPS First Class with tracking is fine for most domestic submissions.
Standard turnaround is 30 business days from receipt. Expedited options are available at checkout.
