I am an independent researcher, writer, and social activist. I am (also) currently pitching a proposal for an ambitious TV series devoted to numismatics.
1. It costs over 2.5 cents to manufacture a U.S. one-cent coin and over 9 cents to manufacture a U.S. five-cent piece. Switching to a less expensive composition (e.g., consisting predominantly of aluminum or steel) would save U.S. tax payers at least $10 million per annum. Note this precedent: in 1982, due to the increasing price of copper, the mint transitioned from the 95% copper/5% zinc compositional ratio for the Lincoln cent to 97.5% zinc/2.5% copper.
2. About 12,800 years ago, multiple fragments of a comet or asteroid collided with North America. As a consequence of this cataclysmic event, perhaps in combination with other factors, 70% of this continent's megafauna, including the woolly mammoth, giant beaver, American lion, scimitar cat, dire wolf, and every species of horse, became extinct. See on YouTube: Randall Carlson's Ancient Catastrophe (Full Documentary).
3. I further propose that the visage of Andrew Jackson be replaced by natural historian and pioneering environmentalist Rachel Carson on the U.S. twenty dollar bill.

4. The rate of species extinction on our planet has been estimated at an alarming 0.1% per year. In conjunction with the special coin designs already planned to commemorate the 250th anniversary of American independence, I propose that a series of special coins be minted to spotlight species currently deemed endangered in the U.S., state by state. I further propose that the denomination for these coins be set at 20 cents, a historical anomaly produced only from 1875 through 1878. The U.S. already produces several denominations that are seldom encountered in circulation: the 50-cent piece, dollar coin, and 2-dollar bill. Most vending machines already exclude these and other denominations and there would be no need to reconfigure their mechanisms to accommodate 20-cent coins. The mintage of proof sets for collectors has in recent years ranged between 400 thousand and 800 thousand per year. I suggest not only that the 20-cent piece be added, but that the total mintage be increased to 1 million for the year 2026 with each state's design comprising 2% (20,000) of that total. I propose that the mintage for circulating specimens be set at 1 million for each design evenly split between the Denver and Philadelphia mints (50 x 500,000 + 50 x 500,000 = 50 million). Rather than the copper-nickel alloy that is used for our 10-cent and 25-cent coins, I propose that the composition for the 20-cent coins instead be bronze, an alloy that is eminently suitable for commemorative pieces and durable enough for commercial deployment.
The designs for each state's special 20-cent piece could be fashioned to illustrate state birds, mammals, flowers, and/or trees on the obverse and an endemic endangered animal or plant on the reverse. So as to reflect the separation between nature and nation, I suggest that the designs omit the mottoes "IN GOD WE TRUST" and "e pluribus unum"; these deletions would also be aesthetically advantageous. Photogenic endangered mammals include the California sea otter (population: ~3000), Cook inlet beluga whale (AK; population: ~330), Florida panther (population: ~200), Texas ocelot (population: ~120), north Atlantic right whale (population: ~360), pygmy rabbit (WA; population: <100).
Note: in 2008, the U.S. issued three separate commemorative coins in honor of, and to support the replenishment of, the American bald eagle.
