@Coindom Do you want to explain me what you want to say by flow?, Sorry me I have hard time to understand what you guy's say by flow. For me are only the lines from center to sides due to the material movement in time and place of the strike. I know many terms are use been new to the collecting. I come to learn more every day and see new varieties. Thanks.
For the coin, me IMO I do not see die crack there on the signature.
