Obverse has an improper alloy mix (horizontal) Tiger Stripe; back looks like a die trail, maybe something on the steps?
I agree with the Improper Alloy Mix on the Obverse.. But I don't know what you are talking about concerning the Reverse
Sorry, I meant die crack - the line above FG I circled and then did a close up of...it doesn't appear to originate from the edge but looks like one to me.
