There is no doubling of any kind on his lips. There looks to be very slight machine doubling on his chin. Why would it matter? The condition of the coin is terrible, anyway. Chris
I think I am catching on to these kinds of doubling, but the lips here were different, so I was curious as to what might cause this...
Like @cpm9ball said, it's machine doubling. It just takes time. You'll catch on. You have to train your eyes. When you have a coin you have a question about, search this forum first. 9 times on of 10, you will find your answer.
