Claire’s coin collection contains fifty 1948 silver dollars. Her grandparents purchased them at their face value in 1948. These coins have appreciated by 7.6 percent annually. How much is the collection expected to be worth in 2025?

We start by identifying what is being asked: the future value of Claire’s collection given annual appreciation and the time span from the purchase in 1948 to 2025.
First, determine the initial investment: 50 coins at face value of $1 each in 1948, so the starting value is $50.
Next, compute the number of years from 1948 to 2025: 2025 − 1948 = 77 years.
The coins appreciate at 7.6% per year, so the future value formula is: Future Value = Present Value × (1 + 0.076)^{77} = 50 × (1.076)^{77}.
To get a sense of the magnitude, evaluate the exponent: (1.076)^{77} ≈ e^{77 × ln(1.076)}. Since ln(1.076) ≈ 0.07327, the exponent is approximately 77 × 0.07327 ≈ 5.64. e^{5.64} ≈ 282 (very roughly).
Thus, the approximate future value is 50 × 282 ≈ $14,100, which aligns with the neighborhood of the given options.
Now examine the answer choices:
- $11,218.27: This is far below the ~14k expectation, suggesting either a much smaller growth rate, fewer years, or an error in calculation. It does not fit a 7.6% annual growth for 77 years.
- $18,987.56: This is significantly higher than the 14k ballpark; it would require a larger effective growth or miscount of years, so it’s unlikely with the given data.
- $14,122.01: This sits very close to the rough calculation around $14,100 and is consistent with 77 years of 7.6% growth starting from $50. Its proximity to the estimated value makes it a plausible match.
- $14,077.16: Also close to the estimate, but slightly lower than $14,122.01. Depending on rounding of the exponent, it could be a contender, though it’s a tad farther from the rough calculation.
- $13,611.18: This is the farthest from the rough estimate and would imply a noticeably smaller growth over 77 years, which contradicts the 7.6% annual rate provided.
In summary, the calculation 50 × (1.076)^{77} yields a value around $14,100, making $14,122.01 the option that most closely aligns with the precise computation, while the other numbers diverge more substantially from the expected result.
