Final answer:
Each U.S. Mint listed (Denver, Philadelphia, San Francisco, and West Point) has at some point produced coins valued at well over 1.7 million dollars. Therefore, all options (a, b, c, and d) are correct.
Step-by-step explanation:
The question pertains to the production of coins by U.S. mints. All four options presented are locations of U.S. Mint facilities, and they each produce coins that have significantly higher values than 1.7 million dollars. For example, the Denver Mint in Colorado (a) and the Philadelphia Mint in Pennsylvania (b) are both well-known for their high volume of coin production.
The San Francisco Mint in California (d) has a long history and is particularly known for producing collector and proof coinage, which could easily surpass the value mentioned. The West Point Mint in New York (c) also produces a large quantity of coins, including gold, silver, and platinum American Eagle coins. Without a specific timeframe or further context, it is reasonable to assume that all these mints have produced more than 1.7 million dollars worth of coins at some point.
Therefore, while the question doesn't specify a particular time period, all options (a, b, c, and d) are correct as they each have had production runs that exceed 1.7 million dollars in value. Furthermore, please note that FIGURE 8.13 and Memory Errors seem to be parts of another question and unrelated to U.S. Mint productions.
