According to experts and coin collectors, the 1960 penny with a clogged G error can be worth anywhere from a few hundred dollars to several thousand dollars, depending on its grade and rarity. Higher grades, such as those classified as Mint State (MS) or Proof, would typically command higher values.
As always, it is essential to have the coin evaluated by a reputable coin dealer or professional numismatist to determine its exact value accurately and ensure its authenticity.
