The National Bank of Kazakhstan issues coins of the national currency of three types: circulation, bullion and collectible coins. All types of coins are legal tender.
Circulation coins are made of base metal alloys and are intended for everyday use by the people. Such coins have a multiple nominal structure of 1-2-5, 10-20-50, 100 and 200 tenge.
Collectible coins are made in small quantities of precious (gold and silver) and non-precious (cupronickel and nickel silver) metals. They are intended for collecting and developing the numismatic (secondary) market. Collectible coins are divided into series and are dedicated to anniversaries and memorable dates, historical events. By issuing collectible coins into circulation, the National Bank preserves and promotes the cultural and historical heritage of the country, perpetuates important achievements and significant events, and carries out an educational mission.
Bullion coins are made of precious metals (gold and silver) of the highest grade and are designed to preserve and increase funds. Their profitability depends on the cost and weight of the metal.
The National Bank, accepting investment coins for redemption, pays to the owner an amount equal to the value of the weight of the metal in the coin.
Features of bullion coins:
- unlimited mintage;
- manufactured without the use of "proof" technology;
- receiving income depending on the cost and weight of the metal;
- accepted for redemption regardless of the condition (scratches, patina, etc.) since the redemption cost is calculated by the weight of the metal contained in the coin;
- are not subject to value added tax.
RECOMMENDATIONS FOR STORAGE OF COINS MADE OF PRECIOUS METALS
Gold and silver collectible coins issued by the National Bank of Kazakhstan are made with a special "proof" technology. Proof quality is the highest standard of coins distinguished by the smooth mirror surface and evenly frosted relief design of the coins.
Precious metals coins must be stored in conditions preventing them from mechanical damage. The recommended storage temperature for coins is from 5 ° C to 40 ° C. It is necessary to avoid influence of the fast-changing temperatures on coins with jewel inserts.
It is not recommended to store collectible precious metals coins in the following conditions:
• Without its original packaging – a hard transparent capsule which is designed to protect the coins from fingerprints, dust and foreign debris that can damage the mirror-like surface of "proof";
• Near household chemicals, cosmetics, medicines. It is especially dangerous to store coins next to the chlorine, mercury, and iodine, since coins might be covered with stains or dark patina.
• In polyvinyl chloride albums (colorless, transparent plastic, thermoplastic polymer), as over time, PVC breaks down, releasing organochlorine compounds which can cause greenish patina on the coins;
• Near banknotes, because of possible content of sulfur compounds in paper, this may cause darkening of the surface of the coins;
In case of necessity to take out coins from the protective capsule, better to do it in special cotton gloves or special tweezers with soft tips only. It is not recommended to clean “proof” coins by yourself.
Bullion coins of precious metals are produced without the use of proof technology. Depending on storage conditions, stains can appear on bullion coins, representing the oxides of metals and microscopic particles of various substances that fall on the surface of the coins. Having these stains on coins does not characterize them as defective. In case of stains on the bullion coins, they can be removed by using special cotton cloths for polishing silver.
When buying coins, it is recommended to carefully examine the coins and make sure that the packaging is intact and that there are no visible defects before signing the control check.
Attention: claims to the quality of the coin after opening the protective capsule by the consumer are not considered.
