It comes in two sets. Set 1 is cards 1-240. Set 2 is 241-261. Set 2 is tougher to find as it was issues a bit later (1987), but neither is that tough. You should be able to find this entire raw set in the $100 or less range, but in order to get all of them in 8's or better you probably have to buy dozens of sets. I know I did.
Just e-mail if you have more questions as I don't check the forum that often.

BTW, even though they are called postcards these cards are regular size. But be aware they actually do come as postcards, 3" x 5", as well. Those aren't the rookie cards and they have postcards backs instead of the player biographies.
