Retaining Value in Collectible Coins

Special collector coins not intended for circulation are being minted throughout the world by old, storied mints. These are sold to collectors at prices higher than face value. So it is quite natural that collectors prefer that these coins retain, or even better increase their value.

Generally, these coins come with extras. Retention of these extras is essential to preserving the value of these special coins.

Some coins come mounted on special mint cards, and sealed by the mint. These cards allow the mint to say something about the coin design, or about the subject of that design. But these cards also attest to the coin’s being genuine. Not only should the coin remain in the mint card, but the card itself should be preserved and kept from damage. Some of these cards also function as a stand, and it is acceptable to utilize this feature if this does not cause damage to the card.

More frequently coins are placed in small display cases that look like jewelry cases. These cases usually house higher quality coins than one would find on a mint card. Unfortunately, any coin in a display case is usually removable. This requires care when opening the case since the coin can tumble out, especially after the coin has been jostled during shipping.

Display cases are designed to be used in showing the coins they contain.

Occasionally, as with the Perth Mint’s Dreaming Series, a special display case is designed. The Perth Mint proudly includes in the description of the Dreaming Series coins information on the exquisite display cases that contain them. These beautiful cases have wooden tops, and rotate open on a single post.

The most uniquely beautiful case of which this author is aware is the one used by the New Zealand Mint for the Gilded Lunar Animal Series minted for Niue. The case has a unique shape, and a definite oriental appearance, making it appear to belong with the coin!

The case used by the Royal Canadian Mint for some $20 denomination proof hologram coins is plastic, and folds into a stand with the coin viewable at a pleasing angle. These cases are longer than most others.

Regardless of the type of display case used for a particular coin, it probably also comes in a cardboard box especially designed for the coin. Boxes can contain words and images, which do not really belong on any display case. Collectors often demand these boxes, and insist they be in excellent condition. Do be careful opening the box, since a slight tear on a flap can alter the value of coin-package combination. Never discard the box that accompanied a coin from the mint.

Often the mint includes a Certificate of Authenticity that gives the specifications for the coin and the total number of coins of that type available for release. This is the mint’s assurance the coin is genuine, at least to the original owner. Coins and Certificates of Authenticity can be separated. In fact, some dealers sell COA’s and boxes for coins separate from the coin. These can then be associated with lesser value coins. One thing that does help is the COA and the box nay have matching numbers, if the COA does in fact have a number. A numbered COA’s is more valued than a COA without a number.

Some sets come in a single case, and may either have one COA, or have one each for the coins. When several coins are together, if the numbers on their COA’s match their value is enhanced.

Mints frequently also include acrylic capsules. Never open an acrylic capsule. It not only offers physical protection for the coin, but often offers environmental protection due to the vacuum inside. Opening the capsule exposes the coin to the atmosphere, which may cause damage at some future time. Unfortunately, these capsules are easily scratched. Avoid unnecessary cleaning of any capsule, and handle only on the edge as you would handle the coin if the capsule were not there. Care for that capsule as though it were a coin.

Many fine examples of these boxes and cases can be viewed by opening coin descriptions on the Perth Mint website. Some other coins mentioned here are from the New Zealand Mint or from the Royal Canadian Mint. Links to these prestigious mints can be found on the Black Spaniel Gallery website. Simply go to and go to the page with mint links.

In coin collecting a good rule to follow is if it came with the coin, keep it with the coin. And always protect the coin and its included materials.
