1897-O - High O - Encircling Reverse Die Crack

I knew that was coming! Cool, from what I understand, die cracks are very common and generally alone do not qualify for VAM. I figured the cracking on this coin was typical on late stage dies. Just wanted to confirm in case I start finding die cracks this extreme. You can see the crack jump from letter to letter, word to word and even through the wings. Start at the last picture, the crack is obvious on the top of the text.

The crack is continual, although you need a loupe and just the perfect lighting to pick up the lighter portions of the crack... especially at the end of America.

Wow! So I have a couple of questions.

How does a die crack on a VAM affect its value?

Can a die crack on what seems to be a VAM disqualify it from being attributed?

I'm guessing that my coin is just a late stage http://www.vamworld.com/1897-O+VAM-3

most of your coin has the die cracks,,Where as SD's show extreme die breaks where metal is comming out of the cracks up into the field, In this case on your coin between the I-T of united there appears a small break, interesting but with such a common VAM the VAM gods have not deemed it listed or significant enough to at least allow its presence known....meaning it doesn't make it a super VAM so it was not worth there time to add it to the listings or give it another assigned number.. still nice coin there
