I like the penny because sellers of goods will just bump up the price of everything to the nearest nickel. Also, sales tax on lower priced items will be quite regressive.

That possibility has been studied based on historic data and found to be false. The perpetuation of the penny and nickel benefit only the mining industry and metals smelting industry. Everybody else sees negative consequences. Most countries retire their low value coinage as inflation makes it useless. For the most part only the US persists in perpetuating the manufacture of coinage that has no value to the economic or consumers, and only because of lobbying by special interests.
