Case in point for why I never buy from the mint. When they make a mistake, as any coin seller is apt to do, you have no recourse. The mint isn't a business, it's a part of a federal bureau and, as such, is unaccountable for its errors. The USPS is as unaccountable and as hard to deal with in the case of their errors, but I have little choice but to deal with them on a regular basis.
