Judo Golden Score: What Is It & When Does It End?

In the sport of Judo, a situation can arise where the regulation contest time expires with the score tied. To resolve this, an overtime period is initiated. This period continues the match with the original scores reset to zero, representing a clean slate. The first competitor to score any point, or for the opponent to receive a penalty (Shido), is declared the winner.

This overtime mechanism serves as a crucial element, preventing draws and ensuring a decisive outcome. It maintains the dynamic nature of the contest and encourages competitors to actively pursue victory rather than settling for a stalemate. Its implementation evolved to address concerns about excessive contest duration and the need for a readily apparent victor for both spectators and competitors alike.

8+ Rare Silver Dimes: What Year Are They? Value & More

United States dimes produced in 1964 and earlier contain 90% silver and 10% copper. Coins minted from 1965 onward are composed of a clad metal: layers of copper-nickel bonded to a core of pure copper. This difference in metallic composition directly affects the intrinsic value of the coin, separating those with significant silver content from those with face value only.

The historical context for this shift lies in the rising price of silver in the early 1960s. As the value of silver approached the face value of the coin, the U.S. government made the decision to eliminate silver from dime, quarter, and half-dollar coinage to conserve the nation’s silver reserves. This change in composition significantly altered the numismatic value and collector interest in pre-1965 dimes.
