We all remember these Bronze-Age beauties, right? Stamp books ordered from Marvel, to be filled with collectible stamps clipped out of dozens of random, concurrent mid-70's issues. Because anything that promotes taking a pair of scissors to your comics can't be wrong...
Let's not dwell upon the hundreds or thousands of dollars of issue devaluation this sort of thing wrought upon many a naïve collector. Value stamps still have a special place in comics history, and there are a few online resources devoted to tracking these babies. If nothing else, this information can be important to any collector of Bronze-Age back issues...knowing which issues to keep an eye out for, to identify whether or not missing stamps are a problem. I've found Rob Anderson's checklists to be very comprehensive, on his Marvel Value Stamp Index website:
Series A (100 stamps)
Issues checklist & Stamps checklist
Series B (100 stamps)
Issues & Stamps checklists combined
So why bring up the antiquated subject of Marvel Value Stamp collecting in the first place? Glad you asked...BECAUSE THEY'RE BACK! Series C began its release on Wednesday, October 4, 2017. This is to be a 53 stamp set, intended to represent 53 different titles of the new Marvel Legacy imprint. Precise information is difficult to come by at this early stage, beyond this Newsarama article which contains an image of the Series C Marvel Value Stamp Album (to be available on Wednesday, November 8, 2017): Marvel Value Stamps returning in Legacy. If a linkable image of this issue checklist becomes available, I'll be sure to post it here.
First observations on the new series, is that we seem to have exactly one specific stamp associated with one specific issue. This is a major departure from previous series, wherein one specific stamp was sometimes available in as many as 6 different books/issues. Even more importantly, removal of the stamps won't affect the integrity of the comic pages themselves. Separate undersized flaps containing the goodies will be inserted through the books' lower staples, allowing for easy access without damaging anything else around them. Although if you ask me, an otherwise mint condition issue that happens to be missing its stamp, is still likely to be valued less in a collector's eyes...
The Marvel Legacy books are being printed with a variety of variant covers, big surprise there. It should be noted that the regular cover copies are the ones slated to contain stamps, while other versions may not...so buyer beware. Another warning should be given about the rash of Marvel's lenticular covers being released as breathtaking homages to the classic covers of yore. Apparently, not as breathtaking as one might've hoped. These covers have been reported as being too thin to properly sustain the optical effect of any single image, resulting in a constant bleeding between both images. Additionally, Marvel's ill-conceived sales ploy has made it nearly impossible for small/average-sized retailers to get any lenticular copies for their customers. So even though their retail prices are supposedly the same as for regular covers, we can expect actual prices to be dictated by the giant comics houses that can afford them (e.g. Mile High, Midtown, Westfield, mycomicshop.com, etc.). It'll be a buyer's market, and the house always wins.
Now that I've had a bit more time to check out Rob Anderson's MVS Index, it's come to my attention that there exists yet another, unofficial "series" of stamps. Inside of John Rhett Thomas' 2006 Marvel Spotlight title, which simply showcased pairs of comics creators for its 12-issue run, there appeared newly-designed value stamps of a dubious nature. Although all 28 of them did feature notable reprinted artwork, there was also a whimsical, tongue-in-cheek quality to their inclusion. Perhaps as testament to how half-serious these stamps were intended to be, no MVS albums for this series were ever even produced. Nevertheless, the pictures themselves ran the gamut from Silver-Age titles to very recent/current characters, books, & events. Examples include New Avengers, Sentry, Araña, Wolverine: Origins, Ultimateverse, Annihilation, Civil War, Planet Hulk, and the Illuminati:
Series 2006 (28 stamps)
Another interesting tidbit the website offers, is a rough evaluation of completed stamp series versus the devaluation of issues that got clipped. Without getting into mathematical examples, the general assumption here is that typical book condition goes from Very Fine to Good by removing a stamp. Here's how Mr. Anderson summarizes this devaluation:
"Basically, with just the difference in value...you could currently buy yourself several complete Marvel Value Stamp Books on eBay."
"...your collection is probably worth somewhere in the vicinity of 80% less with the stamps cut out."
