The most rare and valuable American penny is the 1943 bronze Lincoln cent. It is estimated that only a few of these coins were minted in error, as the U.S. Mint was supposed to be producing coins using zinc-coated steel that year due to metal shortages during World War II. These rare 1943 bronze cents can fetch prices of over $1 million at auctions.
1500 American dollars. I'm not joking that penny is really rare.
The most valuable ones are the 1943 copper penny, and the even more rare 1944 steel penny.
This is considered an "error coin" and is rare. Depending on the "eye appeal", rarity and significance of the error, the penny may be moderately valuable.
It's worth about 3 cents. It's old, but not rare or valuable.
3-10 cents on average. It's not a rare or valuable coin.
it has no value and is by far the most rare
The 1943 steel cent is exceedingly common. The 1944 steel cent is exceptionally rare.
Uncirculated? Maybe 10-20 cents. It's not a rare or valuable coin.
It's worth about 3 cents. Post-WWII wheat cents aren't rare or valuable.
Old coins are valuable because they're old and rare. The 1945 penny isn't worth remarkably more than other coins of its approximate age (in fact, it's worth a lot less than a 1944 steel penny, or a 1943 copper penny, both of which are extremely rare).
The 1943 penny sticks to a magnet because it is made of steel, not copper like other pennies from that era. While a 1943 copper penny is rare and valuable, it is not worth a million dollars. The most valuable 1943 pennies are those mistakenly struck in copper instead of steel and can fetch tens of thousands of dollars at auction.
The sauce has acid in it, which cleans pennies. Keep in mind that a penny that might be rare and valuable has little value if it has been cleaned.
