In general there is no such thing as an "authentic" two-headed coin. Since "Heads" and "Tails" are stamped at the same time on a stamping press that has different dies for the top and bottom, it's almost certainly a "manufactured" coin. If it's done right, it can be difficult to detect the seam.
Authentic certified examples of this coin have a current market value in the $10,000.00+ range.
Please look at the coin again. No authentic 1816 U.S. one dollar coins exist.
7-1-11>>> This is not a US Mint error coin. It's a novelty or magician's coin with no numismatic value.
A "copy" has no true numismatic value since it is not an authentic coin. I feel copies are a worthless addition to a collection.
Many copy's and replicas of this coin exist and have no collectible value. The 1895 Morgan is a proof only coin, the Mint did not strike any coins for general circulation in this year. Authentic examples are valued at $35,000.00 to $60,000.00.
The 1929 Indian Head Half Eagle is the key-date of this 24 coin series. Authentic examples have a minumin value of $10,000.00. It's also well known to have "Tribute Proof" copy's made that are worthless. The coin needs to be seen. Take it to a coin dealer.
Assuming it's authentic and no mint marks retail values for uncirculated coins start at $1,000.00 and go down to $125.00 for a coin in good condition
Values for AUTHENTIC examples in circulated condition start at $5,000.00. If you actually have this coin, I strongly suggest authentication by a known professional grading service..
If it's authentic, with a date of 1847 the coin can only be a 1 cent piece. All Hawaiian issue coins are very well known targets of counterfeiter's I suggest you have a dealer or collector look at the coin.
Yes. An authentic 1862 $5.00 U.S. coin is a gold coin.
Most silver US quarters are not rare or even scarce, but it depends on the DATE of the coin, post new question.
Authentic examples range in value from $8,000.00 to $325,000.00 or more depending on the grade of the coin. Only 1,500 were produced.
