That would be the 7th printing. When you have a series of numbers like that, the lowest present is the current printing. That is done to simplify changing the print run for the next one because all they have to do is remove (as in scratch off) one number rather than change the whole plate. This only dates from the rise of offset press printing.

That one was funny, but I always preferred the Fabulous Furry Freak Brothers & the strips with the cat in them.
