Here are some factors that can affect the value of a 1946-D wheat penny:
* Condition: The overall condition of the penny is the most important factor in determining its value. A penny in good condition will have little or no wear, while a penny in poor condition will have significant wear and damage.
* Grade: The grade of a penny is a numerical assessment of its condition. Pennies are graded on a scale from 1 to 70, with 70 being the highest grade possible. A penny in higher grade will be worth more than a penny in a lower grade.
* Variety: There are several different varieties of 1946-D wheat pennies. Some varieties are more rare than others and can be worth more money.
* Mint mark: The mint mark on a wheat penny indicates the mint where it was produced. 1946-D wheat pennies have a "D" mint mark, indicating that they were minted at the Denver Mint.
