Quora Economic Inquiry: "Could Crypto Replace Cash if Coins are Retired?"

1. Swedish Rounding vs. Digital Compulsion:

Retiring the penny and nickel does not force an economy into cryptocurrency or cashless accounts. As proven in Canada (2012), Australia (1992), and Sweden, physical cash transactions simply utilize Swedish rounding at checkout:

  • Nickel Rounding (5¢): If only the penny is retired, change ending in 1, 2, 6, 7 rounds down; 3, 4, 8, 9 rounds up. Over hundreds of transactions, net consumer impact converges to $0.00.
  • Dime Rounding (10¢): If both penny and nickel are retired, amounts round to the nearest ten cents (e.g., $15.52 becomes $15.50; $15.56 becomes $15.60).

2. Legal Tender vs Voluntary Acceptance:

Under 31 U.S. Code § 5103, United States coins and currency are legal tender for all debts, public charges, taxes, and dues. Private merchants can choose whether to accept voluntary tender like Bitcoin, credit cards, or barter, but non-fiat currencies cannot be legally compelled. Phasing out sub-dime coins preserves the dollar while preventing hundreds of millions in annual U.S. Mint production deficits.
