In the scene at the New Amsterdam, when Lucky first gets out of the car, there is a large white mark on the seat of his coat. This is possibly because no-one brushed off his coat after a previous take of the same scene, in which he sits down on a "snow" covered bench.
When Penny Carrol's things fall on the ground, Pop Cadetti takes her purse and introduces his left hand into it to grab Lucky Garnett's quarter. But after the cut, he holds the quarter in his right hand.
When Lucky asks Pop for the pants, his hand is in his pocket, then out.
Near beginning, one of the guys draws lines on the magazine picture to make pants cuffs. His sitting position changes from sitting forward to leaning back with legs crossed.
When Pop is at tailor's sitting down, the way he holds the pants changes several times.
During the shadow dance, the shadow behind Lucky is visible through him.
