Welcome to the forum

Would you please supply a photo of the complete coin along with the closeup.
This should be automatic with any posting.

Uncirculated grades range from MS60 - MS70 so each coin could grade differently, depending on the condition.
There are also several varieties of the 1968 dollar. Unless you have a high grade, it would not be worth the cost of grading as with over 5.5 million being minted, they are fairly common.

Welcome to the forum Technically a die crack is not a variety although some may call it one. To be a variety, the difference from one die to another has to be in the original die, not something that occurs afterwards. No TPG would recognize a die crack as a variety. At best it MAY be classed as a mi...

Picture is too out of focus to see clearly but going by 2x2, it says there is a die crack by the mouth.

In that condition, your cent might be worth a dollar or so.

Hard to say why but there is no extra value to it.
You could probably remove it if you like.

Agree
Larger diameter and no copper=Texas Cent
See these quite often on US zinc cents.
No extra value but keep as a novelty.

Take it to a bank and see if you can get a dollar for it. They might not accept it though
with no serial numbers.

Please download a photo of both sides, your file won’t open.

There are no dedicated sites that I know of.
You don’t really say where you are from so I can only say that eBay would give you best exposure as it is worldwide.

In that condition, it is probably worth $250-300.00.
It all depends on what someone is willing to pay.

Your search engine was correct. That is a common two letter prefix series with over 1.8 billion printed.
To be classed as a low serial number, you need at least 4 zeros at the start.
Value in that condition is a dollar or two.
