I haven’t really considered this topic, but here are a few initial thoughts:
-I don’t really like the Canadian method (which I believe other countries have used too) of having the 1¢ denomination for all transactions except for cash. If they are going to get rid of the penny, then get rid of it everywhere. Just as when we conduct business in fraction of cents and the final product is rounded to the nearest penny, if you abolish the penny the final products should be rounded to the nearest 5¢ no matter what kind of transaction is conducted.
-The logic to abolish the penny is even more prevalent for the nickel. Therefore, if the penny goes, so too should the nickel. This would mean a shift from dealing in $.01 to dealing in $.1, i.e. units of 10 instead of units of 100. The only coins in this system would be the dime and the fifty-cent piece; the quarter would need to be removed due to using the hundredths place.
-The savings from going to dollar coins as opposed to dollar bills is calculated as a 30 year savings. For the first 10 years the government would actually lose money. And, even the authors of this study admit that the savings are theoretical and may not actually come to fruition.
-Every attempt to introduce the dollar coin has been so thoroughly rejected by the US markets that the government has billions of these coins stored in a Scrooge McDuck style vault. The added cost to businesses, the extra work for bankers, and the simple convenience of paper money have worked together to keep the coins from gaining much traction in the marketplace.
-The government subsidies so many industries, the gov/fed continually introduces a larger supply of money, fractional reserve banking basically creates money from nothing…theoretically, how is the government putting two cents in to the economy to generate one cent any different?
