1. Condition: The condition of the coin plays a significant role in determining its value. Coins that are well-preserved, with minimal wear and tear, are generally worth more than those that are heavily worn or damaged. Uncirculated or mint state coins can be particularly valuable.
2. Mint Mark: The mint mark on the coin indicates the mint facility where it was produced. Pennies minted in Philadelphia (no mint mark), Denver ("D"), or San Francisco ("S") can have slightly different values.
3. Rarities: Certain one-cent coins from 1983 may have errors or variations that make them rare or collectible. For example, coins with die breaks, off-center strikes, or unusual design elements can be highly sought after by collectors.
4. Numismatic Value: Some 1983 pennies may have numismatic value beyond their face value. This can be influenced by historical significance, low mintage numbers, or special commemorative designs.
In general, the value of a common, circulated 1983 US one cent coin is close to its face value (one cent). However, as noted above, certain rare or well-preserved specimens can have increased value to collectors and can sell for higher prices in numismatic markets.
