1973 Red Penny Missing The 1 Completely In 1973 Is This A Find?

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. Coin's Struck Through Grease can also have a blurry image. Sometimes the grease strike will partially obliterate the design, while at other times it will completely do so.



However it can also happen from environmental factors and sometimes hard to tell when the coin has a lot of wear on it like yours to me looks like its environmental rather than from the mint since there is a lot of wear on the surfaces.

Okay I will take another set of pics I don't quite know how to take photos lol

No added value,it is a spender.
