A “monster box” is an industry term for a standard shipping box containing 500 silver coins. Texas Precious Metals produces the only sealed monster box for privately-minted silver rounds in the world. Unlike the plastic boxes from government mints (with breakable vinyl straps), we produce a durable cold-rolled steel custom box with a beige grey matte powder-coated finish. Monster boxes ship in custom plastic tubes containing 25 rounds each. Additionally, Texas Precious Metals produces the only "mini-monster box" in the industry, which is a half-box containing 250 rounds.
