While everyone seem to be in the middle of a Gold Rush Silver has been steadily growing in worth .
Although Silver is still growing in value it will probably continue growing in value.
One investor tried to corner the market in silver but was eventually thwarted.

Coin Grading Service IS it necessary ?
Because of the huge number of coin collectors nowadays, I suggest that for important coins (especially Gold Coins)you should
use a Coin Grading Service.

What is a Coin Grading Service?
This is a professional company that accurately describes and judges the actual condition of the coin submitted to them.

Before Coin Grading Services, coin buying and selling was pretty much a wild west style of business
where you were pitting your knowledge and experience against that of the dealer.
Coins graded by a professional service are normally slabbed in plastic and a description of the coin is included inside the slab.
Some services also value coins.

In the early days the dealer would mark a coin as being (say) VF but with wear on the obverse a coin grading service would grade the coins as GF.
This is not really necessary when buying or selling Bullion Gold Coins
but there are HUGE differences between various grades of collectibe rare gold coins.

So a universally accepted standard arose and this is strongly adhered to by Major Coin Grading Services.
If you do not use a major grading service then you will not know how accurately your coins are graded.

Some dealers tend to over-grade the coins they sell.You should be aware of this and this often shows up in feedback on eBay.
A professional grading service usually encases the coin in a plastic slab and affixes a description as well.

You should use a grading service where you are buying expensive rare coins.

Dealers use the same service to check if their stock is correctly priced (so that they cn still make
a profit without overcharging the customer).

Buyers can also use the same service to check on the authenticity of the coins
and to ensure they are paying the correct price for it.

Some dealers do sell reproduction or fake coins and this is a way to stop that happening to you.

Some of the factors to take into consideration are the age,condition and wear of the coin plus any toning or colouratio.

Companies I recommend are :
PCGS,ANACS,NGC and PCI but ask a major coin dealer and they will recommend a service for you.
However I know that there are other reputable coin grading services.

Some grading services use several experts to grade each coin and some smaller companies only use one expert.

You should of course get a guarantee when you use a coin grading service

If you do not know the service personally then it is wise to check up other peoples experience
with a coin grading service.
