The copyright page has the full number line "10 9 8 7 6 5 4 3 2 1     03 04 05 06 07". Below the number line is "Printed in the U.S.A." with one of several possible printing plant codes - "55","56", "57", or "58". There are also first printings that say "Printed in Mexico.   59". The first printing was so large that it was likely printed simultaneously in multiple printing plants. Below that is "First American edition, July 2003."
Boards are blue with an embossed diamond pattern, and a gray cloth spine with metallic blue lettering. The dust jacket has $29.99 price on the upper corner of the front flap. The dust jacket back has a reddish bar code field on the left side, and the small bar code within has the number "52999". The spine on both the book and dust jacket have the YEAR 5 badge.
More about the number to the right of "Printed in U.S.A": This is the printing plant number, and it signifies the printing press where the American editions were produced. The first three books in the series seem to have come out of a single printing plant. But the Goblet of Fire and the subsequent books in the series had such large first printings that the job was split up between several plants throughout the U.S. and even in Mexico. Also, printing in multiple plants all over the country allows the publisher to distribute the books faster. So far one number doesn't seem more valuable than another for these later series books. One school of thought is that the press runs were so large for Goblet of Fire, Order of the Phoenix, Half-Blood Prince, and Deathly Hallows that they will never be scarce - so nobody is paying much attention to where it was printed. Another thought is the possibility that one printing press may have produced very few books, and that fact could make one printing plant number more collectible and more valuable than another. But so far we see no evidence that this happened.
