The Penny: Is It Worth the Cost of Minting?

The debate over whether to stop minting new pennies is rooted in economic efficiency, public convenience, and the broader impact on commerce. President Trump's directive to the Treasury Department to halt penny production is driven by the fact that each penny costs nearly three cents to produce, leading to a financial loss for the U.S. government. However, this decision raises concerns about potential shortages, changes in pricing strategies, and consumer sentiment regarding the smallest unit of U.S. currency.

One major argument in favor of stopping penny production is the high cost relative to its value. The government loses money by minting pennies, and these losses accumulate to millions of dollars annually. Many countries, including Canada, have already eliminated their smallest coin, shifting to rounding systems for cash transactions without significant disruption. Additionally, the growing prevalence of digital payments reduces the need for small-denomination coins, meaning that fewer people actively use pennies in daily transactions. Cashless purchases would remain unaffected, and businesses could adjust by rounding transactions up or down to the nearest nickel, as seen in other countries that have phased out low-value coins. The Treasury Department could also resume minting pennies if an actual shortage developed, preventing long-term economic disruption.

Public opinion on eliminating the penny has been a subject of research in various studies over the years. A 2014 YouGov poll found that 51% of Americans favored keeping the penny, while 34% supported eliminating it, with the remaining percentage undecided. Another study conducted by Americans for Common Cents, an organization that advocates for keeping the penny, found that a majority of Americans still view the penny as a necessary part of daily transactions. However, independent studies have shown that when presented with the economic inefficiencies associated with the penny, support for its elimination tends to increase. The U.S. Government Accountability Office (GAO) has also examined the financial implications of discontinuing penny production, estimating potential savings for the Treasury but acknowledging that consumer sentiment plays a role in the decision-making process. 

A significant consideration in eliminating pennies is how rounding transactions to the nearest nickel would be implemented, particularly in the case of sales tax calculations. Since sales tax rates vary by state and locality, a uniform rounding rule would need to be established to ensure that taxes applied to purchases do not introduce an unfair burden on consumers. Some states, such as those with no sales tax (e.g., Oregon, New Hampshire, Montana), would experience no impact, while others might need to adjust tax calculations to round to the nearest five-cent increment. This issue has been successfully addressed in other countries, such as Canada, where cash transactions are rounded but credit or debit transactions are still calculated to the cent. If rounding rules are not carefully implemented, concerns about businesses consistently rounding up rather than down could lead to consumer skepticism about the fairness of the system.

On the other hand, critics argue that eliminating penny production could lead to unintended consequences. One concern is that individuals and businesses might hoard pennies, fearing they will become scarce, which could create a shortage of pennies for those who still rely on them for making exact change. Even though fewer people use cash today, those who do - especially lower-income individuals who rely on cash transactions - might be disproportionately affected by rounding policies. If most businesses choose to round prices up rather than down, consumers could experience a slight but cumulative increase in costs. Additionally, the justification for eliminating the penny could raise questions about other fractional monetary values, such as the continued use of the tenth-of-a-cent in gasoline pricing. While gasoline prices are typically calculated at a fraction of a cent for marketing and accounting reasons, the absence of pennies might call into question whether such precision is still necessary or if rounding practices should be reformed in that industry as well.

The broader economic impact of eliminating penny production would likely be minimal in the long run, as businesses and consumers adjust to rounding practices. However, the psychological attachment to pennies, their role in cash-based transactions, and the symbolic importance of preserving all denominations of U.S. currency make this a topic of continued debate. Below is a comparative analysis of the pros and cons of stopping penny production:

Comparison of Arguments For and Against Stopping Penny Production

All things considered, while economic logic favors discontinuing penny production, the societal and psychological implications suggest that the transition should be carefully managed to avoid unintended consequences. The experience of other countries indicates that consumers and businesses can adapt to rounding practices, but any change to the currency system requires careful consideration of both immediate and long-term effects. Public sentiment remains mixed, but studies indicate that with proper education and implementation, opposition may decrease over time.

AI Technical Trustability Update

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
