- Condition: The condition of the coin is a primary determinant of its value. Coins that are well-preserved, with minimal wear and tear, are more valuable than those that are damaged or have excessive wear.
- Mint Mark: The mint mark on the coin, which indicates the mint that produced it, can also affect its value. The Philadelphia mint (designated with a "P" mint mark) produced a significant number of wheat pennies in 1945, so this mint mark does not add much additional value to the coin.
- Rarity: The rarity of a particular coin can also influence its value. While 1945 Philadelphia wheat pennies are relatively common, some variations or errors can be rarer and, therefore, more valuable to collectors.
- Overall, in general, a well-preserved 1945 Philadelphia wheat head penny without any significant errors or variations is likely to have a value of a few dollars. However, rarer varieties and those in exceptional condition can fetch higher prices among coin collectors.
