Nope, the 'crack' has to be either very thick or really desirable from one end of the coin through the subject to the other. Check out this 'spike heads' they are also fun to collect... Just my opinion, you find any more, post them pics!!!

Cracked skulls are the result of cracks in the die that transfer to the coin as raised lines. However, they are usually the highest part on the coin. On worn coins they are often flat and spread. Laminations are defects in planchetts caused by a bad alloy mix, bubbles or impurities in the molten. Laminating coins are in some stage of metal separating from the coin. It appears yours is a lamination. As for cracked skulls, there are thousands of them, literally, just for the 50's.
