The 1909-S V.D.B. penny is a rare United States one-cent coin minted in 1909. It features the image of President Abraham Lincoln on the obverse and the words "One Cent" on the reverse. The "S" indicates it was minted in San Francisco, and "V.D.B." refers to the initials of designer Victor David Brenner, which were placed on the reverse. This penny is highly sought after by collectors due to its limited mintage and historical significance. Only about 484,000 of these coins were produced, making it one of the most valuable pennies in existence, often fetching high prices at auctions.
