In April of 2008 the British Royal Mint has announced that the British coins would feature a new design. Thus British currency officially started changing its coinage. It is worth mentioning that the old designs of British coins were used for about 4 decades. Before April of 2008 United Kingdom currency included coins with the image of Her Majesty The Queen on one side. For many centuries British coins featured the engraved images of kings and queens.

Federal appeals court judges expressed their worries about the fact that blind people are not able to distinguish between a $50 bill and a $1 bill. The judges, however, still hesitate on forcing the redesign of the U.S. currency.

The case rose after a judge stated that the government discriminated against sightless people because it keeps the banknotes in the same color, shape and texture. Although the judge gave several days to the Treasury Department to start solving the issue, while appeals play out, the question regarding changes still remained withheld.

Today on the market there are two main types of rare coins, the first group includes grade rarities and the second group mintage rarities.

Mintage Rarity

This represents a rare coin that was issued in low quantity if compared to market demand.

The main distinction between a planchet and a coin blank is that the former has a raised rim, which is applied to the coin's blank with the help of an upsetting mill. The mill compresses the edge of the coin blank as it is rotated among two beveled surfaces. Errors that occur from planchet include all the mistakes that are a result of a defective blank; this does not depend on whether it has passed or not through the upsetting mill.

Planchet Error

Since 1971, the United Kingdom of Great Britain and Northern Ireland has used a decimal system, one pound valuing 100 pence.

When it comes to precious metals, the most think of silver and gold only. However, this term implies any metal that represents a rare metallic element, which in its turn is both qualitative and has a durable economic value. It is believed that the status of a precious metal depends on its scarcity. The rarer the metal is the more precious the item becomes.

The silver dollar coins, minted in 1799, have at least 11 obverse dies and 17 reverse dies, which are being used in about 23 various combinations. An increased number of silver dollar coins was the result of silver deposited in other sources besides Bank of North America. The amount of deposited silver improved in 1800.

Although the economy of the United States was declining, there was no obligation for the Mint to store silver dollar coins to only one depositor. Interesting to note that today about 16 different types of 1800 silver dollar coins can be found. Probably one of the most interesting among them being the coin where there is a misspelling on its reverse, saying AMERICAI. An important fact is that the dollar denomination was a single silver coin that the Mint struck in the period between 1798 and 1800.

Since decimalization, the coins of the United Kingdom for the first time will feature new designs. The nation will be able to see the major change in the design of the legal tender coins in the late spring of 2008. New designs will be included on coins with denominations from 1 pence to 1 pound. These will feature a more contemporaneous Britain, the one of the 21^st century.
