The 1940-S Lincoln Wheat Cent in MS64RB (Mint State 64 Red Brown) is a high-grade coin highly prized by collectors. Minted at the San Francisco Mint, this copper penny features Abraham Lincoln’s iconic portrait on the obverse and the wheat stalk design on the reverse. It has a composition of 95% copper mixed with tin and zinc, weighs about 3.11 grams, and measures 19 mm in diameter.​

The “Monster Toned” description refers to the coin’s natural, attractive toning—vibrant patina colors that develop over time due to chemical reactions with the environment. This toning can include reds, browns, purples, blues, and greens, enhancing the coin’s aesthetic appeal and often increasing collector value. In this grade, the coin exhibits full original luster with only minor marks or imperfections.​

MS64RB means the coin is Mint State 64, meaning it is uncirculated with a few small marks or hairlines, and “Red Brown” indicates that the coin mostly retains its original red copper color but shows some brown toning. The “Much Better In Hand” comment highlights that the coin’s eye appeal and colorful toning are more vivid and impressive when physically viewed compared to photographs.​

Prices for a 1940-S Lincoln Wheat Cent MS64RB with exceptional toning can vary widely but typically range from around $20 to $60 depending on the quality of the strike and toning appeal. Coins with very eye-catching or “monster” toning that enhances their rarity and visual impact may command prices at the higher end or above, especially among collectors seeking premium copper pennies.​

In summary, a 1940-S Lincoln Wheat Cent graded MS64RB with monster toning is a visually striking, high-grade collectible wheat penny. Its original red copper color with vivid toning and scarce condition make it highly sought after by numismatists, and its beauty is most appreciated in person where the depth of colors truly stands out.
