Coin Supplies & Coin Accessories



Supplies and Accessories

A single gold coin of investment quality could cost you more than $1,500. Make sure to protect your investment with coin supplies and protective accessories that cost as little as $1. Protecting your coins, rounds, and bars with coin holders and cases as well as personally ensuring your precious metals are high quality is the first step toward making sure your investment has the best chance possible to grow over time.


What Size Does Your Item Require?

Air-Tite cases come in two different formats. The first, and most common primary fit type, is the direct fit format. The investor or collector simply places the coin into the holder and the fit locks it in place. The case would then be snapped together for a fit that does not allow the coin to move at all. The second fit type involves a gasket. The gasket would encapsulate the outer rim of the coin or round, giving your precious metal an added level of protection between the surface of the frame and the coin itself. 

A 32 mm will fit many different coins including the 1 ounce Gold American Eagle, 1 ounce Gold Britannia, and many others. To check which Air-Tite container will fit your list check the product description or the below charts. 

We also offer 1 ounce bar Air-Tite cases.

The Benefits of Choosing an Air-Tite Coin Cases

When gold and silver coins began to be collected in earnest in the 1980s, collectors and investors soon discovered that they needed a product which would reliably protect the luster and beauty of their preferred items. They also wanted to have a product that would allow them to display their favorite coins without the need to handle the coin itself. This is how the development of the Air-Tite case came about.

Air-Tite cases are an industry standard today because they are rigid enough to withstand daily handling, yet flexible enough that you can store them virtually anywhere. Featuring the innovative snap-together technology which allows investors to place a coin in the holder and then snap the case together to protect it, you receive permanent protection instantly. Yet if you want to take the item out of its case, you just pop the holder open with a knife or similar thin blade. The unique acrylic material of these cases also prevents the coins from fading over time.
