The Franklin Mint produces some gorgeous collectibles. They are superbly made and packaged, and carry beautiful artwork. They are sold to primarily to collectors, but very seldom to coin collectors.
The reason coin collectors do not buy Franklin Mint products is that they are way too expensive. The exquisite coins, fancy packaging, and strong marketing hype (such as Certificates of Authenticity, plastic capsules for the coins, and elaborate printed historical information) make them desirable for the general public but, in the final analysis, the coins are worth only bullion value.
This means that the value of one Franklin Mint silver coin is equal to the value of the silver it contains. For these Presidential medals, that's about 1.3 troy ounces of sterling silver. Sterling is 92.5 percent pure, so the actual silver content is 1.3 x 0.925 = 1.2 troy ounces. At the going rate of silver, $19.50 US dollars per troy ounce (check it at kitco.com, it changes every day), 1.2 troy ounces is worth 1.2 x 19.50 = $23.40. So one silver medal is worth $23.40 today. If you took your collection to a coin dealer, he or she would probably pay 60 to 70 percent of the silver value. If you could find a collector who likes the set, he or she would probably pay 120 to 140 percent of the silver value.
The analysis above applies to all products from the Franklin Mint.
