What Is Valuable About a Coin?
Not all antique coins are valuable, but some factors make them worth a fortune. Below are the primary factors that contribute to a coin’s value:

1. Rarity
Uncommon coins, be they from low mintage numbers, limited circulation, or special characteristics, tend to sell high. Coins such as the 1933 Saint-Gaudens Double Eagle, of which only a handful are known to exist, have sold for millions at auction.
2. Condition (Grading)
The condition, or grade, of a coin is very important when it comes to determining a coin’s worth. Mint-condition coins (MS-65 and higher) will sell for considerably more than worn coins.
3. Historical Significance
Coins that are associated with significant historical events, like the 1943 steel pennies that were produced during World War II, are of greater interest to collectors.
4. Minting Errors
Coins that have minting errors, like the 1955 Doubled Die Lincoln Penny, are highly desirable because they are rare and unique.
5. Precious Metal Content
Coins composed of gold, silver, or platinum tend to have intrinsic value in addition to their collectible value.
Steps to Determine If Your Coin Collection Could Be Worth $80 Million
If you suspect that you could have rare coins, use the following steps to check their value:
1. Inspect the Date and Mint Mark
The date of minting and mint mark (for example, “S” for San Francisco or “D” for Denver) can be critical.
Some of the most valuable coins by date are:
1909-S VDB Lincoln Penny
1943 Copper Penny
1893-S Morgan Silver Dollar
1916-D Mercury Dime
2. Search for Minting Mistakes
Mint mistakes greatly add to the value of a coin. Most typical mistakes are combination of:
- Double Dies: A doubling of numbers or letters (e.g., 1955 Double Die Penny).
- Off-Center Striking: When the coin’s image is off-center.
- Die Cracks: Cracks within the coin’s image due to worn dies.
3. Evaluate the Condition (Grade) of the Coin
Grading is usually performed by professional companies like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Corporation). Coins are graded from Poor (P-1) to Mint State (MS-70).
4. Test for Authenticity
Use these easy tests to test authenticity:
- Magnet Test: Real copper or silver coins will not adhere to a magnet.
- Weight Test: Compare the weight of the coin to standard specifications.
- Edge Inspection: Look for reeded or smooth edges according to the anticipated design.
5. Investigate Online or Utilize Coin Catalogs
Match your coin with trustworthy resources such as:
- Red Book (Guide Book of United States Coins)
- Online databases like PCGS CoinFacts or NGC Coin Explorer.
6. Obtain a Professional Grading
If you think your coin could be valuable, have it appraised by a reputable coin dealer or send it in to be graded by a professional service.
