1966 penny, small cud on reverse 0

[Vero86]

Got this on change, I think it was cleaned, it's worn, but it has no defined mint mark and a small cud on reverse, does it worth keeping, does it still have value?

That is not a cud, that is a die chip.

Doesn't add much of a premium but keep it as an example if you like.

Horribly polished coin with a die chip not a cud, worth exactly $.01.

I'm with the others....definite die chip and definitely cleaned.  It's a good reference piece for a die chip, but it's only worth face value.

No U.S. coins minted from 1965-1967 had mint marks. They left the mint marks off to discourage hoarding, because the government was blaming collectors for the coin shortage. 

I suggest you buy a copy of "A Guidebook of United States Coins," by R.S. Yeoman, commonly called the "Red Book." It contains a wealth of information that is very helpful to a new collector.

Thank you, I just order the book,
