Clear rivets, wide loop at the bottom of drapery. It's a 1917 (assuming it's a Type I reverse, otherwise I assume you wouldn't be asking). https://www.coincommunity.com/forum/topic.asp?TOPIC_ID=294479
Also has the clear incuse framing squares on both sides of liberty on the wall, the 1916 was not incuse and wore off quickly, so it would be gone in that condition.
