Should I Polish my Bullion Collection?

We strongly recommend that you polish your bullion no more than once a year in order to avoid polishing wear. 

When bullion particularly such as cast bars s professionally polished too often, it can shorten the life span of your items, for this reason we would suggest not brush polishing your collection more than once a year and leave minted bars in its original packaging.


How to Deal with Oxidation in Silver Products

Silver can come in as Fine Silver either Minted or Cast but there are other decorative objects that may be sterling silver which can slowly oxide over time particularly if not kept in a cools secure environment. It is possible to re-oxidize  your collection. Please consult with your local jeweller for this service.


Silver Care & Polish

We recommend you use a polishing cloth to remove mild tarnishing marks in conjunction with silver tarnish removal products such as SILVO for heavier tarnishing.  Use a small piece of cotton to apply the tarnish removal cream by rubbing the silver in small circular motions. Once the tarnish has been removed rinse the silver item in water and wash your hands thoroughly and dry them well.

Please not feel tempted to use 'internet tricks' such a tooth paste to polish your jewellery, toothpaste can cause scratches and damage to silver and gold alike.

We strongly recommend that you polish your collection no more than once a year in order to avoid polishing wear and to again leave your collection in its original packaging wherever possible.

How to Keep Investment Gold

Gold should be kept in a secure  cool environment, particularly care of coinage such as sovereigns should be kept in plastic encasements, coin holders or safe as to avoid any chips or accidental breakage if combibars. In all cases you should keep in original packaging and leave unopened. Although the market value for gold will remain, if your trading or collecting certain historical pieces much attention its placed on the final finish of the item for inspection.

Here are some tips for dealing with gold to prevent product damage and loss of value.

  • Always hold the gold by the edges.
  • Do not remove coins or combibar plates from the packaging (plastic capsule, vacuum pack).Do not touch the surface of the coin or plate, as fingerprints will reduce its value.
  • If you need to touch the product, it is recommended to wear clean white gloves.
  • Do not try to bite the gold to check its softness.
  • Keep the coins in separate holders. Contact with each other can cause scratches and scratches on the coins.
  • Do not allow gold coins or plates to rub against any surface.

A clear plastic capsule will provide not just protection! but expose the product in an elegant way, and will also add extra value.


Weight and Purity Explained

Although the weight of gold and silver is sometimes measured in kilograms and grams, the official unit of weight for expressing the weight of precious metals is the troy ounce (pharmacy ounce). One troy ounce (oz) is 31.1034768 grams. It is worth noting that a troy ounce is not the same as a commercial ounce, the latter being equal to about 28.34 grams.

The purity of gold and silver is measured to the nearest thousandth, i.e. how many parts of a thousand are completely pure metal. For example, the gold sample of a 100 gram plate of PAMP is 999.9, which means that the plate consists of 99.99% pure gold. Another example is the Double Eagle $ 20 gold coin, which weighs 33,43624 grams and has a gold sample of 900. This means that the coin has a pure gold content of 90%, or 33.43 x 0.9 = 30,092 grams.

In addition to the gold sample, the traditional unit of precious metal content is the carat (usually the symbol K is used). The largest possible carat size is 24, which means 99.99 percent or more pure gold. In Europe, gold jewellery is traditionally made in 14 and 18 carat purity, with 14 and 18 parts of the 24 being pure gold, respectively. This corresponds to 58.3 and 75 percent, or 583 and 750 gold samples.
