Wait—did I say “2 coin”? I also mean the 2-cent coin. In the US, that’s a Civil War-era relic. A 1864 2-cent piece in good condition? $50 to $150. A 1867 one? $100+. Sorry, no free lunch—but a nice appetizer.
And in the UK, a 2-pence coin from 1983 with the wrong inscription (it says “New Pence” instead of “Two Pence”) is worth $500 to $1,000. That’s a typo bonanza. Proof that proofreading matters—even in currency.
