What Is Diamond Service Grading?
🏆 The Collector's Choice Since 2021
DSG is dedicated to accurate, reliable grading for sports cards, TCGs, and non-sports cards — at competitive prices with no declared value upcharges.
📋 32-Subgrade Report
Every card receives 32 sub-grades covering all 8 zones — corners, surfaces, and edges — on a clear 0–4 scale. The grade report includes HD front and back imaging of your raw card.
🔷 Polycarbonate Slabs
DSG encases every card in shatterproof, UV-resistant polycarbonate — 25x stronger than acrylic — with a scannable QR code linking directly to the card's grade report.
📍 Right Here in Rohnert Park
DSG ships to and from our address at 5800 Redwood Drive, Suite B, Rohnert Park, CA 94928 — the same location as Baseball Cards & Memorabilia. Drop off your submissions in-store.
