The Silver Anniversary Dallas Cowboys medallion is worth a price close to $75. If you have one that is unopened, it will most likely be worth more money.
5-12-11>> First thing is, it's not a coin, it's a token. It has no denomination and is not legal tender. The front has a left facing portrait of Kennedy with his full name above and the date 1985. The reverse has the "Double Eagles" and the dual dates 1960 & 1985. I found one on the web (Rogers Market) for $2.95 NOTE: Many different types of so-called Kennedy commemorative coins and tokens have been sold, some are gold plated Kennedy half dollars that have been counter stamped with different dates, others are privately minted pieces. But none of them are made by the US Mint and have very little if any value at all.
