These cool medals are made of 90 percent silver and weigh about 19.5 grams. That means they contain (19.5 x 0.9)/31.1 = 0.564 troy ounces of silver (there are 31.1 grams in a troy ounce). Checking kitco, silver today sells at $19.96 US dollars per troy ounce, so the medal contains 0.564 x 19.96 = $11.26 worth of silver.
The above calculations apply only today, the day of this writing. Tomorrow the price of silver will change, so be sure to look it up.
With an $11 silver value, the medal can not be worth less than that. If you tried to sell it to a coin dealer, he or she would probably offer $5 or $6, because the coin dealer needs a margin to stay in business.
Further, if your medal is in absolutely gorgeous condition, like the one in our picture, the value will rise substantially over the $11 silver price. Here are some approximate catalog values that apply today:
worn: $15 US dollars approximate catalog value
average circulated: $15
well preserved: $25
fully uncirculated: $50
