IIRC these are privately-sold sets that include one each of typical coins that were in circulation during WW2. Without seeing them it's not possible to come up with an exact value but it's a good bet that the company that assembled the set didn't include anything that was especially rare. As of 07/2008 some rough numbers might be:
> cent from the early 1940s - about 5¢
> nickel with a large letter over Monticello's dome - about $1. Without the letter, 35¢
> dime - about $1.10
> quarter - about $3.25
> half dollar - about $7.00
The easiest way is to look up your coin by type, date, mintmark, and condition (or grade) in a publication such as ''Coin World'' or ''Coin Values'' magazine. These, as well as others, provide their estimates of current market value. You can also search for coins similar to yours on eBay or other auction sites. These methods require you to know how to find the type and mintmark of the coin(s), and estimate their grade. The publications mentioned above can guide you through that process. Some people also use the ''Official Handbook of United States Coins,'' or similar annual publications for coins of other countries; while these are invaluable references, the price data is often stale by the time they are published. You can also take them to a reputable coin dealer and ask them for an appraisal; most of them will do this for free, if you have just a few coins. Some coin dealers will tell you how much '''they''' will pay for it, which is often 40-60% of the resale value. A good dealer, though, will be able to guide you through the process of determining the type, date, mintmark, and condition of the coin(s).
These coins were the only US nickels that ever contained silver. The amount is small (less than 2 gm) so in worn condition the coins are worth around a dollar for their metal content.If the coin is in better condition, check its date and see the question "What is the value of a US nickel?" for more information about prices.
About $1.90 or so for the silver content. Keep in mind though that for low purity coins like war nickels, most coin dealers offer substantially less than spot on them.
Take it to a coin shop and there are books showing coins and their value.
Chances are, you have a 1947 Swiss 20 Francs coin. These coins are common and worth scrap gold. They contain 0.1867 of a troy ounce of gold and are 90% pure. And worth about $300 in gold melt at the time of writing.
One can learn about value of old coins on the website Coins About. Most coin value guides give you retail prices; that is, they tell you how much coin dealers are selling the coins for.
These coins do not have a minted value and do not appear in coin catalogues, but they are collectible. The only helpful suggestion I can make is to take it along to a local reputable coin dealer for valuation.
That is the value just for the gold in the coin, not as a coin.
Which liberty coin?
Take the coin to a dealer or look in a book on coins for the value.
The circulation of a coin does not drop its value eg. 50p coins from 2012 Olympics.
Coins of another country have no value in Pakistan.
No, for silver coins as the value of silver changes the value of the coin changes. The same is true for gold coins.
Light that coin do pass when thrown on India is light pass when thrown on world.
That is far too broad a question to be answered in this forum. Check your local library for a coin catalogue for Irish or World coins.
You don't. You don't EVER clean a gold coin and you don't clean a silver coin. Cleaning ruins the value of coins! If it has any collector value at all it will be demolished by a cleaning. Cleaning can take a $100 coin into a $10 coin. It will never, ever improve the value of the coin unless you literally dug it out of the ground. Do not clean coins.
There are several factors that determine the value of gold coins. One factor is how much gold is in the coin. Gold is valued by weight, so the more gold the coin has, the higher the value will be. Also, the age of the gold coin. Older, rarer coins will be worth more.
