There are a number of print sources: the famous Red Book, from Whitman Publishing, and the Krause Guide, from Krause, are two of the best-know examples.

For pictures, mintages, and such, I've found www.CoinFacts.com to be very useful.
On the "heads" side of US coinage there is a date, that tells you when the coin was made.
Minted Denver, CO.MoreA "D" on any coin minted since 1906 means it was minted in Denver, Colorado. Other mint marks you may see are:"P": Philadelphia (but current Philadelphia pennies, and Philadelphia coins before 1980 except wartime nickels, don't have mint marks, so it gets confusing)"S": San Francisco (on older coins and modern proof sets)Coins minted over 100 years ago may also have an "O" for New Orleans, "CC" for Carson City, and very old gold coins may have a D or C on them but you won't find any of them in change!
The mint mark that you will find on the 1961 Washington quarter is the letter "D" and it is located on the reverse side of the coin just above the letters "ER" in the word "QUARTER". These coins were minted in Denver, Colorado. The 1961 Washington quarter was also minted in Philadelphia, Pennsylvania but in 1961 Philadelphia was not putting a mint mark on the coins produced there.
Please look at the coin again. You almost certainly have a state quarter honoring the admission of one of the early states in the Union in 1788. These coins were minted in 1999, 2000, and 2001 - look near the bottom of the back side for the minting date. Huge numbers of state quarters were minted so any that you find in change will generally be worth only face value, 25¢.
If it was minted in 2009 and later, the date and mint mark along with the phrase " E Pluribus Unum " are on the rim and not on the obverse or reverse of the coin.
All coins have a date that they were minted, so by looking at the coin carefully, you will find the date the coin was minted.
British Edward VII (1902-1910) Sovereigns and Half-Sovereigns were minted at the Royal Mint London, Ottawa, Melbourne, Perth and Sydney Mints. The coins minted in London have no mintmark. The Sovereign and Half-Sovereign coins minted elsewhere have a mintmark "on the ground" below the horse and above the date. The coins minted in Ottawa have a mintmark "C". The coins minted in Melbourne have a mintmark "M". The coins minted in Perth have a mintmark "P". The coins minted in Sydney have a mintmark "S". The letters BP to the right of the date is the designers initials (Benedetto Pistrucci) who designed the St George and the Dragon scene.
Australian coins minted at the Melbourne Mint do not have a mintmark.
You can find one stamped on the coins minted for Panama. They use dollars but call them "Balboas". They actually use coins minted by the US mint in the exact same sizes and denominations as American coins and most denominations of the coins show an image of Balboa on them.
Try the "Standard Catalog of World Coins, 1701 to 1800" published by Krause Publications.
Quite simply, there were no US dollar coins minted that year.
It's counterfeitNot necessarilySometimes it's very difficult to find the date on a coin. For example, US $1 coins minted since 2007 have the minting date on the coin's edge rather than on the face. Some current low-denomination German coins have almost microscopic dates that are hard to see unless you have good eyes and know where to look.
That would depend on the country of origin, the coin and the mint concerned. Not all coins have mintmarks. They are usually used when the same coin is minted at two or more different mints. Coins minted at foreign mints will nearly always have a mintmark.
Answer All coins are considered worth something depending on how many of that particular coin was minted in 1943. You can find this out by buying a book on old coins, and it will tell you how many were minted that year and what your coin is worth.
On the "heads" side of US coinage there is a date, that tells you when the coin was made.
Any 1942, 1943 or 1944 Australian Threepence, will have the "S" (San Francisco) or "D" (Denver) mintmark on the reverse of the coin, on the right hand side, just below the fourth digit of the year. Any coins minted in Melbourne will have no mintmark.
If it's a US quarter minted in 1965 or later, it's not silver (there are silver coins minted in "proof sets", but these came in a special labeled display case; you're not going to find one in pocket change). US quarters minted in 1964 or before were partly (about 90%, I think) silver.
