You may already know this..............but tags like this were used to trade beaver pelts for items at a trade post. There are many odd things on this tag.
#1 "CN", what does it stand for? Not "HB" Hudson Bay. Not "NW" North West. Not "AFC" American Fur Co.?
#2, Most tags are made on a common number, ex: 5, 10 20, 50, 100..........Not "73", unless this is a date or a traders tag number.
#3, 13 stars?
#4, "W" w/crossed swords. Most traders took "happy" symbles as their mark,(beaver, butterfly,flower, etc...), not War symbles.
My best guess is a modern copy/fake used by someone in furtrade re-enacting/ living history. Kind of a reproduction business card!
