How do you know an error coin is legitimate?

The only legitimate way to know is for them to tell you. All other methods are based on generalizations, and are often in error.

If the "penny side" is copper-colored, then it is probably a magician's coin manufactured from a quarter and a cent, in which case it has no collector's value. On the other hand, if it has a cent reverse where the quarter reverse should be, it may be a legitimate error coin. This determination and evaluation should be made by a reputable dealer in error coins.

Then it would be an error coin. I suggest you take it to a coin shop and have them look at it to determine whether or not it is actually an error coin.

A "misprinted" coin is called an "error coin". These occur when there is a malfunction of stamping machines or a case of human error. The result is a coin which is not perfectly struck or has a design flaw. In order to give an accurate estimate of value, the exact nature of the error must be known. Please examine your coin again and then submit a new question giving a description of the error.

No, it's not possible that a double-headed quarter with two such diverse dates could be a legitimate Mint error. Dies are destroyed, if not worn out through usage, by the end of the year in which they are used. The coin in question is almost certainly a novelty or magician's coin.

It's worth 5 cents, or 1/20th of a dollar. If it is a "collectible" coin, it may be worth more, but we'd have to know what year it was struck, what mint mark it has, and what condition it is in. And we'd need to know if it is in any way double struck, cracked die, or one of the other things that qualify the coin as a mint error, which will increase its value.

Mint error coin that has become famous in coin collection circles.

You are talking about an extremely rare occurrence for any coin. I would need to know the type of dollar you have and date to estimate a value - a local coin dealer could give you a ballpark, but with error coins the value is in what a collector will pay. Needless to say if it is a genuine coin, it could have substantial value.

It is extremely unlikely that an Australian decimal coin with minting errors survived the inspection process and went into general circulation. The closest acknowledgement of an error on an Australian 2 cent coin is that in 1967, 1968 and 1981, the designers initials were left off the reverse of the coin. If it turns out that you do have an Australian coin with a genuine minting error, take it to a reputable coin dealer for…

There are two well known clubs that specialize in error coins. One of those are American Coin Collectors and the other being American Numismatic Society.

All error coins need to be seen. Take to a collector or coin dealer.

If the "error" or "misstrike" is nothing more than the word TRUST spelled with a V, this is not an error, but artistic license; the designer chose to use the Latin alphabet, which used a "V" in place of our "U" and omitted the equivalent of our "V" entirely. In that case, the coin is worth anywhere from $16 in well-circulated condition to $800 in near-pristine state. If the error is anything else, such as…

You should probably take this to a professional coin dealer for an accurate valuation. The value would depend on the condition of the coin, the perceived cause of the error (e.g., is the "4" missing because of a die error or because someone went at it with sandpaper and ground it off the coin), the extent of the error, and how "interesting" the coin looks. A collector of error coins would probably pay at least…

There are many different printing errors in the production of currency. In order to give an estimated value, the nature of the error must be known. If you do not know what the error you have is called then you could take it to a coin dealer who also deals in currency.

One reputable error dealer and expert is Ken Potter; see the Web Links to the right for a link to his…

Unless the coin has a minting error, it's just face value--one dollar. The most common minting error is missing edge inscriptions on the George Washington dollar.

It depends on the error. If the coin is damaged and the 4 is missing, it takes away value of the coin. If the coin isn't damaged its possible it is a grease filled die, a minor error that adds only cents to the coin's value. If worn/damaged the coin is worth about 2-3 cents. If uncirculated the coin is worth about $2-3 with the grease filled die.

If you had a legitimate reason and need to know, then the resources to find out would be available to you. Since it seems you do not, it can only be assumed that you have no legitimate need to know.

If the coin has a "Coat of Arms" and the words FLORIN - TWO SHILLINGS, it is probably an Australian coin. The "Coat of Arms" would be supported by a kangaroo and an emu. If your coin is a genuine minting error rather than a trick coin, you may have something of value. A reputable coin dealer will be able to give a valuation based on inspection of the coin.

A coin such as this needs to be seen to determine if it a true mint error or not. I suggest you take the coin to a coin shop and have it appraised.
