The TAA & GT Railroad started as two separate railroads ~

The michiganrailroads link shows the projected 1881 route for the new Toledo, Ann Arbor and Grand Trunk Railway.
Most Wilcox baggage check tags, that I've seen for sale, sell at $100.00 and up. It really depends on which railroad it's for and the condition of the tag. Search "W.W. Wilcox baggage tags" for a general idea.
