You have what's known as a "Magician's Coin".
This is NOT something that was done at the Mint.
This was made by altering two normal coins and gluing the altered pieces back together. Use a magnifier to check just inside the rim on one side of the coin -- you are looking for the seam where the two pieces were joined -- it could be on either side of the coin.
This novelty item sells regularly on eBay.com for a couple of dollars.
One such coin has been certified as an authentic mint error and I believe it sold for (or was valued at) about $25000. If one coin was struck with these mismatched dies, there must have been more, but perhaps only one slipped past the QA inspectors.
Your local coin shop will have the address for all the major grading and certification services or you can find their ads in any of the regular numismatic publications. If it is real, you won't be able to sell it for 25 grand without certification from PCGS or ANACS.
They cost about $8 in novelty shops.
the eagle cion
It is worth nothing. You could try and take the two headed coin to a coin expert. But it is just a misprint.
This will be worth a minimum of 800 dollars or more. This is a rare coin and is really only worth what a dealer will pay for it or a private person on auction sites.
It all depents in the year n condion of the coin. I have 1959 silver quarter double head in both sides n I done my homework n its nt that much u could email me a pic at email@example.com
Depends on how many made it into circulation and how much off center it is. Is it both sides or only one side?. Which side if only one side? What condition is the quarter in? What state?
At minimum, it currently has $3.50 worth of silver in it. Without either seeing pictures of both sides, or a very detailed description of both sides, it's impossible to provide any meaningful estimate of value.
No US silver dollars or bullion "eagle" coins have an eagle on both sides. You may have a privately minted piece, a fantasy coin, or a "magician's coin" made by cutting two genuine silver dollars in half like an Oreo cookie and swapping the sides.
It's called a Walking LIBERTY half dollar, and the fact that it has the eagle on both sides means it's a magician's coin. Please see the Related Question for more information.
i have this coin, its worn but can see the date clearly and picture on both sides, is it worth anything ?
I'd guess that it's an 1851 Mexican quarter peso, but I'd need to see it to be sure.
On both sides there is: George Washington - USA's First President' Bald Eagle - USA's national bird or on the newer ones they have a states name when it became a state and the year the quarter came out.
