⚖️ Why We Started

As lifelong collectors, we saw that true archival-quality currency displays were often overpriced, while cheap acrylic and PVC holders risked damaging valuable notes. We knew there had to be a better option.

By combining numismatic knowledge with modern 3D printing and precision design, we created Serial Shield 3D™ — a collector-focused line built around clear Mylar® windows, clean presentation, reusable construction, and practical storage solutions.

Today, D.D. Collectables offers collector-grade currency frames, modular PETG storage systems, and custom 3D printing services in San Antonio for collectors, hobbyists, and creators nationwide.

Our mission remains simple: help collectors protect, organize, and showcase what matters most without compromising quality, clarity, or affordability.

🛠️ How Our Frames Work

🧱 3D Printed Precision Frame

Each frame is 3D printed for a precise fit around standard U.S. banknotes (6.14" × 2.61"). An internal ridge helps keep the note properly positioned inside the frame.

🪟 Crystal Clear Mylar Windows

Each frame includes hand-cut Mylar windows on both sides, available in 4 mil, 7 mil, and 10 mil options. This clear polyester film allows full front-and-back visibility while helping reduce direct handling, dust exposure, and surface contact.

📎 Collector-Grade Mounting Tape

The Mylar is secured using archival-safe double-sided tape placed away from the note itself. The note does not come into contact with the adhesive.

🔩 Screw-Down Assembly

Each frame is secured with black-plated thread-rolling screws for a clean, durable, and reusable design. No glue, clips, or magnets are used in the frame assembly, and the frame can be reopened when needed.

🗄️ Modular Storage Systems

Our modular PETG storage systems expand the same collector-focused approach into coin capsules, graded slabs, bullion rounds, 1 oz bars, and other collectible storage needs. These systems are designed for practical organization, stackable storage, interchangeable drawers, and clean presentation.

⚠️ Why Material Choice Matters

Our frames use Mylar polyester film for clear visibility and a cleaner presentation. Unlike many soft “floating” style holders, the window material is rigid, clear, and designed for collector-focused display use.
