1970-D Washington Quarter Struck on Roosevelt Dime Stock Mint Error ICG VF20 – Rare Wrong Planchet U.S. Error Coin

The 1970-D Washington Quarter Struck on Roosevelt Dime Stock Mint Error is a fascinating and highly collectible U.S. Mint production anomaly that showcases one of the most dramatic wrong stock errors encountered in modern American numismatics. Certified by ICG in VF20 condition, this remarkable error coin was mistakenly struck on thinner dime stock intended for Roosevelt Dime production instead of the proper quarter planchet, creating a distinctive and historically important mint-made error highly sought after by collectors.

Wrong stock and wrong planchet errors occur when a coin is struck on metal intended for another denomination, resulting in abnormal weight, thickness, strike appearance, and overall dimensions. In this extraordinary case, a Washington Quarter was struck using Roosevelt Dime stock, producing a noticeably different appearance compared to a standard quarter. These major production errors are far scarcer than common die cracks or off-center strikes because they require a highly unusual breakdown within the U.S. Mint manufacturing process.

Struck at the Denver Mint during the early clad coinage era, this 1970-D error also represents an important transitional period in American coinage history following the removal of silver from circulating dimes and quarters during the 1960s. Mint errors from this era remain especially popular because they highlight the challenges associated with modern mass coin production during a changing metallic composition period.

Certified VF20 by ICG, the coin retains strong remaining detail while displaying the distinctive characteristics associated with this dramatic wrong stock error. Collectors of genuine circulated mint errors often appreciate moderate wear because it demonstrates the coin likely entered circulation before being discovered, adding an additional layer of historical intrigue and authenticity.

The combination of a major wrong stock error, Denver Mint origin, certified authenticity, and strong collector demand makes this piece an outstanding addition to advanced U.S. error coin collections.
