Δ The holder is made of acrylic plastic with a non-yellowing agent. It's composed of two parts of highly durable, crystal clear pieces: cover or lid and the base that snap together.

The white color rig [my favorite color because it reflect the light when taking photos and also give an attractive border to accent the coin] is made of an inert cross linked polyethylene and serve a couple of purposes; it secures the coin in the holder and creates a barrier against air contamination.

Both the holders and rings are PVC free which provide superior long-term protection. I recommend using cotton gloves when handling the coins to prevent scratches, accumulation of filth and other elements that damage the surface of the 1½ pence.

The Air-Tite coin holders, is the only type with a perfect custom ring of 12 mm diameter to encapsulate the 1½ pence pieces that at least I have located in the numismatic market without making a large investment.

This type of encapsulation can be used for various purposes, is intended for those collectors who do not want to invest large fees in professional encapsulation, either because little numismatic value of a coin, do not feel confident with the accurateness of these companies, or simply it is possible keep a vast quantity of coins in a small space. Of course, each individual has a different point of view.

Δ The album is black vinyl notebook style with 6 vinyl pages [for 6 display cards] and a protective slipcase measuring 6½ x 6½ x 2¼ inches, a small and convenient size. If you desire to purchase these numismatic accessories just contact me for details. 

To assemble the album insert the Air-Tite holders into the display cards [made from chipboard laminated with velour on one side and black embossed scuff resistant paper on the other] by placing the holder on a flat surface and pressing the display card over it with the velour side facing up. Apply pressure until the holder is flush with the back of the display card. When all holders are placed in the display card, slide the card into the Air-Tite coin album plastic page.

However, if you want your collection professionally certified and encapsulated, in the next chart I posted those companies that for one reason or another, based on my personal experience, I think are beneficial to the preservation of 1½ pence in several aspects, without mentioning the one to choose, because that is for each individual to judge.

Δ  Safe deposit boxes at banks, have generally been the safest way to securely store a collection and protect it from risk of loss or damage. [1]

After the collector have decided which method to use to resolve condition preservation or practical storage issues, it must be ready to consider the best method of securing the collection from risk of loss and also climate conditions issues. Exposure to extreme climate conditions of all types can potentially damage coins. For example in America, humidity, prevalent in Florida [where I live and I can confirm] but not Arizona, is a risk to coins with silver, copper or nickel content, as well as to Proof examples. Storing desiccants with the collection is advisable as an extra measure of coin protection.

My two options range from banks vaults to in home safes. The last method has one disadvantage, apart of likely it will be carried away during a brake-in, the safety of your coins from fire damage. While most in home safes may not actually burn, they will get superheated inside if consumed in flames. In such instances, the plastic holders could melt and expose the coins themselves to damage.

So, back to the first method, choose a safe deposit big enough to comfortably fit your collection. For collectors who choose this method, are providing safety for themselves and their families, while safeguarding the coins from risk of loss or damage in a way that allows the greatest degree of enjoyment potential since bank vaults or safety deposit boxes provide the security and peace of mind that is most important to you and yours collectibles, specialty if the collection is of significant value, then it is advisable. At the end, the safety of your family and valuables take precedence over the need to have full-time access to the collection. However it's just my personal advise and every individual, must assess additional ongoing expenses to choose the method most compatible which could be meaningful depending of the person's goals.
