Go to the Laminations part of the list. There are a few different types. http://www.error-ref.com/part-v-planchet-errors/ No real large premiums for Laminations unless they are major Laminations and eye appealing.
If that is a Die Crack it is interesting. Only value would be what a collector is willing to pay for it. Don't plan on retiring with what you can get for it though
I agree not lamination, but a vertical die crack. The crack was filled pushing the crack medal upwards.
Significant laminations that have folded over and were struck, and lamination fragments that have detached (along with the planchet itself) are among the most desirable, especially if they detached from dates and profiles Here are a few of mine
