It looks authentic. It should weigh 2.28 grams and the copper core should be visible on the edge. Most such errors are struck on blanks, rather than planchets. I'm not sure whether the flattened appearance of Lincoln's head and coat is due to a weak strike, a grease strike, or post-strike abrasion. Weakness in the strike would not be due to any press malfunction. It's simply because a dime blank is thinner than a cent blank and is therefore closer to the minimum clearance of the dies at their closest approach.
