I'm trying to identify differing print runs on these, so anybody who owns any, please dig them out and take a look. On the copyright page it always states (in English) the first printing date.  Underneath that it lists (in Japanese) the actual printing: 第2版 (2nd), 第3版 (3rd), 第4版 (4th), etc.  See pic:



The only difference I've noted on the boxes themselves is that sometimes the copyright date gets updated.  The Basic Set is for sure an exception in that they didn't list the revised (errata incorporated) version as a 2nd print... you actually have to look through to books to see if errata is applied or not.  The box is different on the first print as well, lacking the "発売元 : 株式会社 æ–°å’Œ" (Publisher: Shinwa Co., Ltd.) text in the front bottom right corner like later printings.  I'm mostly curious about the Expert Set because I don't have any early printings on it.

Any help would be appreciated!
