TOUGH book to find. Have only found 3x smith variant in the last 4 years, and no Moore variants ever. I notice one (Moore) sold for 60 quick last night. eBay has been a ghost town on this book.
I have an explanation. All-New Ghost Rider #1 wasn't released until March 2014, so for roughly two years you were looking for a comic that didn't exist.
Now that pre-heat speculation right there. Look for a comic that hasn't come out yet!
! My bad, confused my timeline with the Alejandra GR series.
There's only 8 or 9 series. Not sure how you got confused.
Marvel at its best.
