Grease strike throughs are very common for the most part, they're probably the most common error type besides laminations, and so only grease strikes which have obliterated large areas of the coin have any decent good added value. The exception are coin series which are rarely found with errors of any kind. Some otherwise still sell when they like yours are missing parts of the design and some like that have a following such as 2005-P Kansas "In God We Rust" quarter missing the T for trust. This error type occurs when grease gets on the planchet or die and is struck into the coin. The grease can come from any number of sources including the minting press, which has lots of moving parts that get oiled, or it could come from the planchets themselves, which historically have at various periods in time been coated with a small amounts of oil.
