I found this it may help http://en.allexperts.com/q/Coin-Col...f-Dollar.htm

Question
I found a gold 1973 Kennedy half dollar recently. What made it stand out to me was that it has a picture of Abraham Lincoln imprinted on one half of the face side of the coin and on the other half the dates 1964 and 1984 on the other. It is in excellent condition. I haven't been able to find any information on it so any information you could give me would be great.

Answer
Hi Megan, these were thinly gold plated and stamped with the extra effigy after they left the mint for sale as souvenirs by people or companies trying to making a quick buck. They are worth whatever someone is willing to pay for them and have no real collector value as an original coin.
Cents were also stamped after they left the mint by people or businesses that sold them for $1 as souvenirs. Many feature John F. Kennedy, Abraham Lincoln, the Moon landing or a U.S. state outline. They have value only as curiosities and are worth a dollar at best depending on amount of wear and collector demand.

yep I also have those as well they look nice but thats about it
