This is a relatively low-grade, circulated example of this scarce 1891 Z1-B variety. This could mean this piece stayed in circulation a while or became someones pocket-piece. This example shows three digs in the lower arrow feathers. This example also weighs 2.95 grams and has a 1.27 mm thick planchet.
 
I don't get counterfeit IHCs in my inventory very often, and when I do they usually sell quickly. This example should fill a nice type hole in your collection.
