Sorry, i read the first series date on some of the sale sites. My bad
But it is books like ASM #19 (MJ in a spider man outfit), ASM #257(MJ reveals she knew Peter was Spidey), ASM #259 (Mary Jane Watson's backstory, american Versions in worse quality than mine are going for $40-$60, yet i found the Canadian version for less than $15). Spectacular Spider Man #110, and Peter Porker, the Spectacular Spider Ham #3. Nothing uber rare like an Amazing Fantasy or ASM #252 (i did find a 252 from the same seller as my 257, but it looked like it had been pulled out of a sewer and stomped on by small children every day since its was printed, and thus not worth keeping or framing). I do wonder if people not knowing how to price them also tanks the value, as people will always buy the cheaper option, and make them easier for someone who needs anything for it,to move it faster.
Mine are all the books that have the higher cover price than the American version (due to the exchange rates being different than earlier in the 80s),mostly the 75c or 95c versions. yet they arent worth near as much as the American version in 80% of the cases of my 5. I get ASM #19 isnt worth much to anyone outside of MJ fans, but when a 4.4 American version goes for higher than my 6.5 Canadian Version,it seems like the whole price variant thing is just a big myth (if that makes sense?). The only book i have that is worth more than its American verison is Peter Porker The Spectacular Spider-Ham (which has gained interest since Spider-Ham was in the Into the Spider-verse Movie). That one is worth almost 3x as much as an American version in the same quality (i did manage to get mine for dirt cheap becuase the person who had it, didnt even know CPV existed and just assumed it was an American version)
I'll admit that I dont mind picking them up for cheaper than the American Version (although less were produced for the Canadian Market when the Variant occurred, and stores could return the unsold ones, whereas comic stores cant (hence the difference between the ones with the spider man logo and the ones with barcodes), but weren't as big of a distributor as newsstands until about mid 1986).
It is still estimated that less than 5% of the newstand versions even exist any more due to things like improper handling at the store, and parents getting them for kids who didn't care for them (i have an Action Comics from December 1946 that i got for practically dirt cheap because a kid wrote their name on the front cover. I didn't really care as an Original Action Comics from Dec. 1946 is almost always worth framing for the simple fact it survived from 1946). I just dont know if me, as a huge Spiderman fan, should frame the CPVs or keep them in their dark, dry drawer until the demand shoots up.
