I just heard a promo for tomorrow's NPR Morning Edition. They are doing a story on buying presidential coins from the U.S. Mint to get frequent flyer miles. I didn't catch everyone they are interviewing, but I did catch that Ben will be on it. Should be interesting to hear NPR's take. At the end of June they did a story about how the U.S. Mint was mandated by Congress to make $1 coins that nobody wanted. I remembered thinking at the time it wasn't true that nobody wanted.
