It's actually old Victoria so later 1800s to 1900 on the "gapper" or maybe just defaced coin. Cool find! The Wannamaker item is great. Is it an employee badge from their store?

George - at first I thought it was silver based on the pic you text'd to me, but based on its size (about 30mm??) and look in the pics you posted, I'm sticking with it being 19th century British copper - maybe a mid-1800s penny like the example below.
