Square Coin Tubes — 20-Coin Holders for 40–41mm Rounds (Pack of 6)
Product description
What you get: A pack of six square coin tubes, each sized to accept up to twenty coins with diameters between 40 and 41 millimeters. These cylinders are intended for commonly collected pieces such as American Silver Eagles and many US silver dollars.
Materials and protection: The tubes are molded from archival-safe plastic that resists degradation and helps preserve coin condition. Under each lid sits an Intercept-style foam ring designed to actively inhibit tarnishing and corrosion for up to fifteen years while also cushioning the top coin to prevent scratches.
Design and use: The caps use a rotating closure that secures the contents with a simple twist for removal and reseating—no heavy pressing required. Their square exterior profile maximizes stacking efficiency and keeps collections neatly aligned on a shelf or in a safe, while the transparent body lets you see the top and side of stacked rounds.
Capacity and dimensions: Each tube holds up to 20 rounds of 40–41mm diameter. Overall external dimensions measure approximately 3-1/2 inches by 2 inches by 2 inches, making them compact and easy to store in drawers, safes, or storage boxes.
Practical notes: Best suited for standard-diameter 1 oz bullion and similar-sized medallions. The foam ring both reduces tarnish risk and prevents top-coin abrasion, and the square shape aids neat organization. Keep in mind very large or unusually struck pieces may fit tightly or not at all.
