The D mint mark indicates the coin was made in Denver, but the date is equally important in determining its value. Since 1956 or so the Denver Mint has churned out huge numbers of pennies so anything minted in the last 55 years is unlikely to be worth more than face value. If the coin is older, please post a new question with its specific date.
Denver, Colorado.
The "D" Mint Mark identifies the Denver Mint. There were no one cent coins minted in Denver in that year; they were all made either in San Francisco ( S Mint Mark), or in Philadelphia ( no Mint Mark). Double-check your coin with a strong magnifying glass.

US pennies minted in Philadelphia do not bear a mintmark, unlike those produced in Denver ("D") or San Francisco ("S").
