We might call a doubled die coin "double struck" because it was "minted" twice with the same die. This results in a minting error. A date or part of the design can be "repeated" on a coin thus minted. A coin that escapes the quality control screening and makes it out into circulation can be worth some bucks.

If a coin is a double die as a result of the die itself having an inconsistency it is worth far more than a coin that was simply struck twice.
There are no known 1953 "Doubled Die" errors at this time, but machine doubled errors exist for all U.S. coins. Take it to a coin dealer for an assessment.
Many of the coins are valued in price close to $1,500. The exact price of the coin will vary depending upon its condition.
A doubled die is a condition normally not found with modern practices found at the United States Mint; other countries' mints, as well as private mints, may still produce doubled dies. A doubled die is when a double image of the coin is created on the die used to strike the coin. In years past a master die was made by copying a plaster copy of the final coin to steel, reducing the size to the correct size of the coin in the process. This master positive would then be struck into another piece of steel, producing a die. That die would then be used to produce more steel positives, which would be used to create more dies, until all the dies that would be needed would be created. (The steel was hardened along the way to allow each result to strike more than one copy of die or positive image.) Because the force required to transfer the image was more than earlier equipment could handle, each positive or die would be struck multiple times. If anything changed between strikings, a double image would be created and transferred in subsequent strikings, eventually to the final coins produced by the doubled die or set of doubled dies. In some cases, unused dies from the previous year would be modified, replacing the previous year with the current one; if the previous image was not completely obliterated, a doubled die condition would also occur. A doubled die is not the same as a doubly-struck coin. Many coins are actually struck multiple times, either intentionally (in the case of proof coins) or unintentionally (such as die bounce).
To date, no certified examples of a reverse doubled-die 1966 Lincoln cent exist. Mechanical doubling is likely what you see, not a true doubled-die error. Mechanical doubling is the most common type of doubling on U.S. coins and is most often confused with doubled dies, this doubling is extremely common with numerous examples being produced on all denominations every year. It's value is only what someone is willing to pay.
What do you mean "double faced" you mean like a doubled die error? Or do you mean it has heads on both sides? If it has heads on both sides it is not a mint product but rather a "magician's coin" and is privately made and pretty much worthless. If it is a doubled die error, please provide the year and mint-mark of the coin so we can better identify if it is a known error and how much it is worth.
Well, all "dramatic" means is that its easier to see than some doubled dies. Since by nature a doubled die will be the same on all coins that have been struck by that particular die, it doesn't mean that this example of X year's quarter's double die is better than other examples of the same year, merely that the doubling of this particular die variety is easier to see than others. Some coins have dramatic doubled dies such as the 1955 wheat penny doubled die which is easy to see with the naked eye, while others such as the 1943-P nickel doubled die is much harder to see and generally requires magnification to appreciate.

Not all 1943 nickels are double die errors with doubled eyes. The doubled eye variety is a well-known error for 1943 Jefferson nickels, but it is not present on all coins from that year. If you have a 1943 nickel, it would be best to have it authenticated by a professional coin grader to determine if it is the double die variety.
It means, Double Die Reverse

In circulated condition, the 1983 Lincoln memorial penny is worth just 1 cent unless you have a doubled die. It's the uncirulcated and proof coins that hold some value depending on the mint: Philadelphia: $0.25 Denver: $0.25 San Francisco: $2.75 (Proof Coin) An Uncirculated doubled die from Philadelphia is worth nearly $300
A double die coin is a die which was hubbed (the design impressed on it from a hub), and then hubbed again but the designs did not match up exactly. That leaves two or more "images" on the die. The original image is called the secondary image, because the newer image is higher in relief. There were many reasons for the second hubbing, from the multiple-squeeze hubbing process, to replenish the design, or to change the date and use the die for another year. Since the mid 1990's, the US Mint uses the "single squeeze method", so there is little possibility of new hub doubled dies. Many of the "doubled die" coins you see (struck after 1997) for sale are merely strike doubled (or MDD) coins and not worth a premium. This is especially true of the so called Doubled Die state quarter. There are many classes of hub doubling: Offset, Rotated, Pivoted, design differences, and more. In the case of a Doubled Die, the second image is "added" to the first. In the case of Strike Doubling, the second image "smashes" the first image.
Simple answer is: 1909-S / 1909-S V.D.B. / 1914-D / 1922 no D / 1931-S and the 1943 Bronze and 1955 Doubled-Die error coins.
Well, first off it is a Washington Quarter dated 1934, it is in mint state condition. Coins are graded on a scale from 1-70 with 1 being nearly recognizable and 70 being perfectly flawless. Mint state means the coin has no evidence of circulation, however, it might have scratches from hitting other coins in a bag or a roll. Doubled die obverse means that there was a mistake when the master dies were made and if you look closely parts of the legend are on there twice. Die 4 is the designation of the particular doubled die, certain dies might have slightly different doubling. ANACS means that it was graded by ANACS.
If it is certified by one of the recognized authorities on error coins, it could be worth up to $385. That's what the latest copy of the Numismatic News Coin Market lists for the 1972 doubled die variety in Uncirculated condition. Even the slightest amount of wear will reduce that value dramatically. But it is possible that you have a much more common (and basically worthless) example of "die bounce". The doubled die error occurs only when the doubling is actually on the striking surface of the die and all coins struck by that die will show identical features.
