If this damage happened during minting process,the reverse should show some kind of impact too,right?Thanks in advance for all replies
Your reasoning is wrong. Something like a large die break or cud struck during the minting process would produce weak detail on the opposite side from insufficient metal flow, but that is about it. On the contrary, a coin damaged while in circulation would be apt to show damage on the opposite side because there is no die to prevent such damage from occurring. The semicircular mark you see on the obverse probably came from a coin counting or wrapping machine. Chris
