Some of the boxes you can tell the series by the inserts advertised. it may be possible to tell otherwise by stuff like the item # or other design differences, but I don't know of any guides.
The box shown is shrink wrapped, but not "sealed" at one time a bunch of people would put some sort of filler in the empty boxes and wrap them with a shring wrapping kit. Makes them a lot less fragile for display.
