> What I don't get is why the US Mint would care one way or the other for the concerns of credit card companies.
Hard to say what their reasoning is. It could be pressure from the credit card companies. Or it could be that someone at the mint decided they don't like the idea of people gaming the system.
At the end of the day, it's not a positive-value economic activity. And if enough folks started buying coins for face value just to churn credit card points, there would be financial losses for the mint/and-or the credit card company.
