As a subject matter expert in the field of numismatics, which is the study or collection of currency, I can provide you with a detailed explanation regarding the composition and weight of pennies and how many it takes to make a pound.
When considering the weight of pennies, it's crucial to distinguish between the different materials used in their production over the years. The U.S. one-cent coin, commonly known as a penny, has undergone several changes in its composition since its inception. The primary materials used in pennies have been copper and zinc.
Step 1: English Answer
The composition of a penny has changed over time. Initially, pennies were made almost entirely of copper. However, due to the rising cost of copper, the composition was altered to include zinc. The current composition of a U.S. penny is a zinc core with a thin outer layer of copper. This change in composition affects the weight of the penny and, consequently, the number of pennies in a pound.
Copper Pennies:
- Weight: The original copper pennies weighed approximately 3.11 grams each.
- Number per Pound: Given that there are 453.59237 grams in a pound, you can calculate the number of copper pennies per pound by dividing the weight of a pound by the weight of a single penny. This results in approximately 145 copper pennies per pound.
Zinc Pennies:
- Weight: Newer zinc pennies are lighter, weighing about 2.5 grams each.
- Number per Pound: Using the same calculation method as for copper pennies, you would get approximately 180 zinc pennies per pound.
It's important to note that the actual number of pennies per pound can vary slightly due to factors such as wear and tear, which can reduce the weight of circulated coins, and manufacturing variances.
Additionally, the information you provided about quarters is interesting but not directly relevant to the question of pennies. Quarters are made of a different composition and are heavier than pennies. The number of quarters in a pound is a separate calculation and would not affect the number of pennies in a pound.
In conclusion, the number of pennies it takes to make a pound depends on the material composition of the pennies. For new, unused copper pennies, it's about 145 per pound, and for new zinc pennies, it's about 180 per pound.

New, unused or uncirculated copper cents weigh about 3.11 grams each or about 145 copper pennies per pound. New zinc cents are much lighter and weigh only 2.5 grams each yielding about 180 zinc pennies in a pound. And there are about 80 uncirculated quarters in a pound.
