1974 Kennedy Half Dollar with a mark

[zhome888]

1974 Kennedy Half Dollar with a mark, that looks like a straight line, on back left from the foot holding the leaf to L in "HALF".
It was kind of hard to capture the line in a picture. Some pictures did not have the line in it.

Thanks.

It appears to me to be a "Polish Line". Doesn't look bold enough or strong enough to be a die crack. Neat find... but it won't add any value to it really. Just a novelty more than anything!
