The Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
The Forgotten Silver Kennedy Half Dollars. Released into circulation in the mid 1960's and 1970, silver Kennedy half dollars represent the end of an era in circulating silver US coins. Additionally, these early halves are significantly more valuable than today's modern half dollars. The opportunity to you is most people don't realize, or remember, they contain a large amount of silver. Let's start with the first year 1964, a very special year. In 1964 the new silver Kennedy half dollars were introduced and contained a hefty 90% silver content. The minimum value is $6.00 each.
At the time of writing, a silver dime is worth about $2.50, a silver quarter is worth about $6.25 and a silver half dollar is worth about $12.75. However, the prices depend on the price of silver.
