I dont' think the Marvel Milestone copies of Action 1 sell very well at all. In fact, I don't think anyone has ever sold one.
I meant the AF #15, ASM #1, X-Men #1, etc....
well I'm pretty sure the Action #1 reprint hype is fueled by the EBAY sale of the Action 1 CGC 9.0 being sold on ebay. Due to the rarity and high value realized by THAT sale vs the relative commonness of the Marvel keys, it doesn't seem likely that Marvel Milestones and other Marvel reprints will have similar spikes in value.
Do you think that there are some bidders (on the reprints) who actually don't know the difference?
Perhaps, but there are many that are clearly marked "reprint" in the header that are still going for plenty.
I think it's a mistake to list them now. The spike is likely due to the sale of the real thing, and that auction is over. Another one will come up for sale at some point (not a 9.0, sure, but another copy). Get them slabbed now if they're slab-worthy so you're ready when the next real deal gets auctioned.
So basically Superman is hotter than Deadpool now
