If your 1945 Penny Worth is worn, has lost its luster, and lacks detail then you need to find out the grade of your wheat penny. If the penny is heavily circulated and worn, it is probably in Good (G) or Very Good (VG) condition only, and is worth a few cents. In Fine (F) or Very Fine (VF), Lincoln’s hair and coat might still show minor wear but still be able to clearly discern the details of it, so it will be worth slightly more. Coins that are uncirculated (MS60 and above) have excellent full details, little to no wear and good luster and are the rarest. If definitive grading is required, treat the coin to professional grading services like PCGS and NGC.
