1956 Lincoln Cent was caused by an over-used die being polished at the mint what's worth please? i found this one in a different web site look like a same they say: Most over-polished dies come from the Denver Mint in Colorado and most of the examples are missing part of the coin's normal design. They also display "abraided" die characteristics (from over-use) because these Mint Errors were the result of the Denver Mint, extended the life of the working die, to save money. So mint employees would file and polish the dies. Often, this resulted in some areas of the die to be poorly struck and missing certain parts of the coin's design.

Your coin is worth 3 cents for looking nice, no premium for yours being abraded/overused. In the 50s, ALL the dies were being overused.
