Testing Gold
The various methods of testing gold allow the expert to determine the accurate value of an item. If you are selling jewellery for cash it helps to have a basic understanding of this process.
For the expert buying gold for cash, the Acid test has entered the english language as the ultimate proof. For the gold jewellery buyer the principle is simple. Acid will start to dissolve base metal into a vivid froth but will not dissolve gold.
Acid testers come in sets of bottles. Each bottle contains a different mixture of acid and each mixture contains a chemical indicator that tells you the standard (purity) of the gold. They are designed to measure the purity of the gold to within 10% and with practice results to within 5% are attainable.
When assessing the value of scrap gold items it must be remembered that only unhallmarked jewellery needs to be tested. Prior to testing all items must be filed with a steel file and acid applied to the filed area. If a customer forbids you to file then you cannot test it. However there will always be a discreet place to file the jewellery that is not noticeable.
Gold is not magnetic so all jewellery should be skimmed with a strong magnet and discarded if magnetic. Gold is also very soft and high carat is slightly softer than low carat. Some experienced jewellers will file an item very gently as they understand that steel is so hard that any file seems to bounce off it. Other jewellers may heat jewellery to observe the colour when cooled. Fine gold will not lose their lustre, lower carat gold will become dark, with 9carat turning almost black – they can of course be returned to their original shine by polishing.

Frequently Asked Questions...
What would happen if the world operated under one form of currency?
What economic impacts (good & bad) would the world encounter if the entire planet operated under one form of currency?
Several (long-shot) assumptions have to be considered... so PLEASE READ before answering:
1. All countries are allies/neutral amongst each other. So no rogue nations or crazy-dictators who oppose the world currency. In other words, all nations have stable governments (doesn't just have to be a democracy - just STABLE).
2. Anti-counterfeiting methods are optimal. This form of currency is 100% counterfeit-proof.
3. The currency is NOT backed by gold any other type of precious metal.
4. All forms of existing currency, such as the dollar, pound, yen, etc are obsolete. Of course persons who owned such had them converted to the new currency fairly.
5. A multi-international "Federal Reserve" monitors the production of the new currency where 12-nation-districts print the currency. This organization operates similar to the Fed in the US.
Answer:
Since stabilization was already a premise to this question...not a whole lot would change. Counterfeiting is not the only form of foul play so I would imagine we would see plenty of cheating and unfair manipulations. America would still largely control the world interest rate, but international relationships would become very strained due to disagreements over inflation and unemployment. A move away from capitalism would be necessary because as we already know, capitalism only works when there are many different players acting alone, not all trying to act as one.
...I could go on forever.
