I have been collecting everything Star Wars since I was a kid in 1977. I was putting together a full run of the Hasbro Comic Variants but have decided to list a lot of them in the thread. These were tricky to find because most collectors kept the action figure sets intact that contained the comics. A few times, I actually bought the 2-packs for the comic. They are tricky to grade and price. Many of them don't have much of a sales history online. My prices on these are based on how hard they were to find, condition (of course), online sales/availability, and whether they are keys/semi-keys. This is a really fun set to chase and I will probably still pull ones I find in back issue bins.
Also, I have come across some Dark Horse Star Wars Canadian Newsstands over the years in my bin searching. These are also really hard to value and I am tempted to keep them. There are a bunch of listings from one seller on Feebay for $75 each. I'm not sure if that is a realistic price or not. I will put one up tonight (much lower than $75) and see if it sells.
