So long, penny! Trump orders US to ditch 1-cent coin after decades of complaints

I was curious if there were any downsides and asked perplexity.

Getting rid of the penny could have several potential downsides:

1. Increased nickel production: Eliminating pennies might lead to increased production of nickels to fill the gap in small-value transactions, which could be more costly since nickels also have a negative seigniorage[9].

2. Disproportionate impact on low-income families: The poor, who tend to use cash more frequently, could be more affected by price rounding, potentially facing a "rounding tax"[6].

3. Rounding up of prices: There are concerns that businesses might routinely round up prices to the nearest nickel, creating an informal tax on consumers[1].

4. Loss for charities: Some charities have historically benefited from penny donations, although modern alternatives like credit card "roundups" may be more lucrative[6].

5. Environmental concerns: While penny production has environmental costs, increased production of other coins like nickels could also have negative environmental impacts[7].

6. Potential economic impact: A study in Canada, which eliminated its penny in 2013, found that rounding imposed a small but measurable cost on consumers in grocery transactions[6].
