It was really a pretty little coin: The English 6d of Oak sprigs and acorns ~ The sixpence, known colloquially as the tanner, or half-shilling, was a British pre-decimal coin, worth six (pre-1971) pence, or 1/40th of a pound sterling. The first sixpences were struck in the reign of Edward VI in 1551 and continued until they were rendered obsolete by decimalisation in 1971.
When you make the decision to invest in precious metals you ought to try and buy gold coins. Gold bullion comes in all forms but it may be easier for you to buy gold in the form of coins instead of bars when you are starting out. It is better to check gold prices first before you buy gold coins.
