One area of newsstand discussion that I find is often overlooked is in respect of annuals. There is a lot of excitement, say, for regular Amazing Spider-Man newsstand issues later in the run with issues like #694 commanding huge premiums and even finders fees.
In my experience, although going back about 5-7 years, some of the last newsstand ASM annuals were at least as scarce but rarely if ever attracted attention.
The GCD doesn't have any newsstand versions listed for annual 35, 36 and 38 for example:
To my knowledge, #37 and 39 were not produced as newsstand copies which, if still the case (it's a long time since I last looked) is itself an indicator of relative scarcity. I've never seen a 36, but owned a 35 and 38 in my time. Both are nothing special as issues in themselves and they barely scrape $8 sales as direct editions.
But a quick check of eBay, Google, Amazon, Mile High, Mycomicshop etc etc shows not one single newsstand copy available to purchase. 29 direct editions in the 33 results for annual #35, and all the sales are also directs:
It's the same for #38
So, if I was Chuck I would probably feel justified slapping a 100x premium on these issues in newsstand. They do appear to be that scarce comparative to their direct edition cousins. But as far as actual buyers goes, no one seems interested in collecting them. I sold a large ASM newsstand run to a fellow collector but they didn't want the annuals. It's almost like annuals 'don't matter' somehow.
Anyway, just some rambling thoughts from me. If you find an ASM annual in newsstand for #35 and 38, you'll likely be holding a comic of some comparative scarcity. Which no one, it seems, wants!
