The value of a penny with no mint mark is generally one cent. These pennies are the common cents that were minted in Philadelphia. Older (i.e. pre-1950) Philadelphia cents can be worth more but it depends on their date and condition.
Cents struck at the Philadelphia mint don't have a mint mark.
A penny has a value of one cent unless it is a collector's item and then it is worth more. That question is FAR too broad. To know the value of a coin you need to have its date, condition, mint mark (if applicable) and country of origin.
Without knowing the date, this coin has no value to a collector. So therefore it's value is face value.
With no mint mark, 25c to $5 depending on condition. With an S mint mark below the date, $1.50 to $33.
