The 1870 Two Cents coin is a notable example of a trial piece that was produced as part of the United States Mint's exploration of new coin designs. Known as a pattern coin, it was struck to test public response and assess potential circulation viability. The Two Cents denomination was later officially minted, but the 1870 variants, including the trial coins, are highly sought after by collectors due to their rarity and historical significance within U.S. numismatics.
