The line "Science-Fiction Adventure in" is the dead giveaway, as the revised prints moved the word "in" to the second line. There are some rules in the 1977 print that didn't make their way to the revised printing, notably the random X-boat route table.Look carefully at Book 5 as you may also have a first print of that book. Easy way to tell is to look at the copyright page for a mention of pages 17-52 being changed. If that mention is NOT present, then you have a first print. The first print commands a bit of a premium over the later prints, but more as a curiosity than anything else. The starship design sequence (pages 17-52) was messed up in the first print.Special Supplement 2 was part of Challenge Magazine. It's quite often sold by itself, but without the rest of the magazine I doubt you'd have many takers if you sold this seperately.Supplements 4 and 12 are somewhat scarce for different reasons. Supplement 4 is the most popular supplement while Supplement 12 is the least popular. In general the larger supplement numbers had lower print runs. In the case of the supplements I believe they tailed off to one printing of each book around Supplement 10. Yet it's popularity that drives the value of the supplements more so than scarcity. You simply see more of these than the other two.Adventures 9 and 12 tend to have a slight premium over the other adventures, especially Adventure 1. Unusually, you have two copies of Twilight's Peak, which was notable as being the only 64-page adventure in the LBBs.In terms of value though, Blackmoor's got it right. The scarce item in the entire group would be High Guard, and only if it was the first printing. However, even then what knocks these down is condition. They've been played (naturally) and the core rules are missing their box. If these were all pristine then you would be looking at about $80 for the set.
