Check the listing for details. 1937-D (No D) “D over 1” Lincoln Wheat Penny Error. Color: BN, Made in United States. Listed at 399.99 USD. The 1937-D (No D) D over 1 Lincoln Wheat Penny Error is a rare and unique coin that was minted in Denver in 1937. To my knowledge, this is the only 1937 wheat penny with this particular error. An obvious Denver mint mark directly under the “1” in 1937. This small cent coin is made of copper and features a business strike type. The error occurs when the die designer accidentally struck the 'D' mint mark over the 1, resulting in a coin that is missing the 'D' mint mark from its normal location. This error coin is valuable to collectors and numismatists for its rarity and historical significance. Please check out the pictures, and let me know what you think. I will ship in protective hard case. I will also include shipping, on me! Thanks for looking. :)
