I think the dot pattern, and where they are located (generally not in the borders), is what I look for in black and white cards. The fluorescence issue would be what I would look for also. The paper stock has to be period and is often a dead giveaway. A lot of times fakes will feel rough and not smooth (the way hundred year old paper should feel.)
