Dumb Question On One Ounce Gold Bar "Wrappers"

Coins have these "wrappers" for protection. In a sense, .9999 gold bullion bars do not need that protection.

Pure gold, by definition, does not oxidize or corrode, or even tone, so they do not need protecting from the air. Gold coins, particularly those made for circulation, are not .9999 fine but are diluted to make the metal stronger, but this also makes them more vulnerable to toning. And gold bars do not necessarily need to be protected from scratches and dents the same way as collectable gold coins do, since people usually do not "collect" them as individual items like coins, but merely as pieces of gold. Who cares if your gold bar is scratched and dented, so long as it still weighs 1 ounce?

Coins, being round, are also kind of awkward to store in square boxes or containers, so putting them in square or rectangular holders make them easier to store. Bars and ingots are already rectangular, and are usually designed to be literally, physically stacked on top of each other easily.

The only benefit a "wrapper" for a bullion ingot provides is as assurance of authenticity from whoever it is that made or sold the ingot. Of course, if a counterfeiter can make a realistically fake gold bar, then making a fake plastic wrapper for it should be simple for them, so I'm not entirely sure how much assurance such a wrapper can actually provide. Conversely, a gold bar entombed in a slab of plastic cannot be readily examined and tested for authenticity.

In short, there are many reasons why gold coins "need" these wrappers, and gold bars do not.

There are similar storage options for Ag bars and they may be available for Au bars as well.

Air-Tite has a confusing (at least to me) product page that indicates the holder is for "1 oz. Silver Bar
Royal Canadian Mint .999 Gold Bar (1 oz.)". It doesn't quite make sense to me as 1 ozt Ag bars and 1 ozt Au bars aren't the same size, but I could be misreading the product page.

Wizard Coin Supply carries most of the Air-Tite product line, so you might try contacting either them or Air-Tite to see if they have capsules for 1 ozt Au bars.

That's why I said they aren't the same size.

The confusing thing is that the Air-Tite product page indicates the capsule is for both a 1 ozt Ag bar and a RCM 1 ozt Au bar.

After looking at the Air-Tite site a bit more, I found this page, which indicates that Air-Tite's 1 ozt Ag bar capsule is 50.8mm x 29.41mm x2.49mm and a RCM 1 ozt Au bar's dimensions are 50mm x 28mm x 1.5mm. So, I guess that Air-Tite thinks their capsule is close enough in size to use for a RCM 1 ozt Au bar.

By the way, that page also lists the dimensions of other non-RCM 1 ozt Au bars and the sizes don't seem to be as standardized as the sizes for 1 ozt Ag bars are. So, finding a capsule for a particular 1 ozt Au bar could be challenging.
