We can thank the recently released MCU Movie Thor Ragnarock for the continual rise in value of this comic book. Thanks to the movie, the Valkyrie character has grown in popularity. Avengers #83 was the first appearance of the Valkyrie in the comics. This Silver age comic is one that is sometimes overlooked as the heroes of the story are all female.
Hicollector recommends you purchase this book at a 7.5 or better as better conditioned copies of the book are seldom easy to find.
