Question
Found a double headed 1968-d Kenendy half dollar in my grandfather's/father's (and now my) coin collection.

Is there anyway to tell if it is real or fake? I don't see a seem but the weight is 14.17 g. Of course I weighed it with a regular food scale.

thanks for the help!

Answer
Hello Katie,                             

This is a very common question I have been asked a number of times in the past.   

They are not rare and it is not an error coin. I have experience with these coins and have seen them in Quarters, Half Dollars and Nickels.  

These two headed, or Two Tailed coins are Trick coins, sometimes called Magicians Coins.

All the ones I have come across are machined out on one side carefully keeping the edge intact, while another coin is thinned and slightly reduced in diameter to remove the outer edge. The smaller and thinner half is then placed in the hollowed out half coin.

Look with a good magnifier and light source, where the lower field on one side of the coin, meets up to the edge. They can be force fit or glued together. Another check is weight; an actual nickel blank weighs 5 grams.

Sometimes they are made as a novelty to sell, or to fool people on a coin toss, or just a machinist apprentice practicing his trade. I have also heard of them being sawed in half and glued together, but the sawed ones are easier to detect.

They may sell for .50 cents and up to $2 dollars in a shop. Again they are not rare, and are not in demand by coin collectors.

The modern process the US Mint uses makes it virtually impossible for an HEADS (obverse) die to be matched with anything but a TAILS (reverse) die in the presses used to stamp out coins.

If you still want a dealer to look at the piece for you just write and  give me the nearest large Cities, some postal zip codes and telephone area codes I will refer you to an expert in your area.

The weight should be 11.50 grams for the normal Half dollar yours may have the seam obstructed with lead solder or something if it so heavy.
I hope this information helps.

Good Luck
