A penny for your thoughts? If it’s a 1943 copper penny, it could be worth as much as fifty thousand dollars. In 1943, most pennies were made out of steel since copper was needed for World War II, so the 1943 copper penny is ultra-rare. Another rarity is the 1955 double die penny. These pennies were mistakenly double stamped, so they have overlapping dates and letters. If it’s uncirculated, it’d easily fetch $25,000 at an auction. Now that’s a pretty penny.

• Pennies made in 1943 were mostly steel.

• The material of the penny is all that is important.

• Some pennies are rare and valuable.

• Make sure to collect your pennies for further auctions.

Sir Isaac Newton was contemplating the universe in his garden one day in 1665 when he noticed an apple fall from a tree. Newton wondered to himself, “Why should the apple always fall to the ground? Why does it not go sideways or upwards but directly toward the Earth’s center?” After much contemplation Newton concluded that objects are pulled to the Earth through a force that he called gravity, which means heaviness in Latin. On July 5th, 1687 Newton formally expressed his law of universal gravitation in series of books called The Principia.

• Isaac Newton had many important achievements.

• Apples have played important roles in historical events.
