Hello there! As an expert in the field of numismatics and economics, I'm here to provide you with a detailed and accurate answer to your question about the value of $100 worth of pennies. Let's dive into the specifics and explore the different factors that can influence this value.

Firstly, it's important to understand that the value of a penny is not solely determined by its weight or the material it's made from. While these factors do play a role, the value of a penny can also be affected by its rarity, historical significance, and condition. For instance, a penny from a certain year might be worth more than its face value if it's a rare coin or in excellent condition.

Now, let's consider the scenario you've presented. If we assume that all the pennies weigh 2.5 grams each, and you have 18,000 pennies, that would indeed amount to $180. However, this is under the assumption that each penny is worth its face value of one cent. But what if the pennies were minted before 1982? This is a significant factor because pre-1982 pennies are made of 95% copper, which can make them more valuable, especially if they are in good condition.

Assuming that all the pennies were minted after 1982, you would have 180 USD, as you've mentioned. However, if they were minted before 1982, the value could be significantly higher due to the copper content. The value of copper fluctuates, but let's consider a hypothetical scenario where the copper content of each penny is worth more than its face value. In such a case, the 18,000 pennies could potentially be worth more than $180.

Now, let's talk about calculating the value of 100 pounds of pennies. The weight of a penny can vary slightly, but on average, a penny weighs about 2.5 grams. Therefore, 100 pounds (which is 45,359.24 grams) would contain approximately:

\[ \frac{45,359.24 \text{ grams}}{2.5 \text{ grams/penny}} = 18,143.696 \text{ pennies} \]

If we take the face value of these pennies, that would be:

\[ 18,143.696 \text{ pennies} \times 0.01 \text{ USD/penny} = 181.437 \text{ USD} \]

However, this calculation doesn't take into account the potential value of pre-1982 pennies or the current market value of copper. To get a more accurate estimate, you would need to know the specific composition of the pennies in question and the current market value of copper.

In conclusion, the value of $100 worth of pennies can vary greatly depending on several factors, including the year they were minted, their composition, and the current market value of the materials they are made from. It's always a good idea to have a collection of pennies appraised by a professional if you suspect they might be worth more than their face value.

Now, let's move on to the translation of the answer into Chinese.
