How to Check the Value of Your Coin
Condition: A coin with no wear, no scratches, and a sharp strike will be worth significantly more than a heavily circulated one. You should look for details like the sharpness of Franklin's hair and the distinct lines on the Liberty Bell.
A professional grading service like PCGS or NGC can provide a certified grade, and the Coin ID Scanner app can help you determine the grade by pic.
Look for Errors and Varieties: After checking the general condition, you should carefully examine the coin for any of the errors mentioned above.
Check the Mint Mark: The presence or absence of a 'D' or 'S' mint mark can have a significant effect on the price, as the mintage numbers for each mint are different.
