Is that $20 sale legit? There is nothing special about this book.
Yeah. Can tell from the listing title that it was an eBay sale from the seller Mile High Comics. It was from the height of Inhumans speculation before the failed TV show and before the movie was cancelled. Since there are various Inhumans comic series it can be hard to auto match many of the sales to the right series/book - which was the case here. I was, however, able to find a bit more recent sales data which rightly puts the price down to more like $1 for raw NM. Thanks!
