Jefferson with beard

I opened a 1959 P OBW on Jan.2nd 2008 and noticed that 60-75% of the nickels obverse had what looked like a short beard under the chin of Jefferson.The hair is little bubble looking stuff.One of the coins even has the bubbles going around the outline of Jefferson and it makes the forehead and nose look dubbled.Some coins have the the bubble stuff on the ponytail as well chin/neck.The coin in the picture was a random pick I didn't search the roll to pick the best one to photograph it was the top one.
