So here's some interesting data. There's two listings for AP versions of the Montes signed foils on Ebay right now. One is a sold listing for $650, and the other is a guy who supposedly has two copies and two have been sold already (though I can't find anything in his history showing prior sales.) Dude also claims to have a CBCS signed copy although that was never offered by ComicSketchArt. Both are graded copies and CGC 9.8s. His username is vetcomix. We have a JoeNavy from earlier in this thread who said he bought half of the stock when these came out. Also interestingly enough, these APs are listed as the "Variant Cover F", not the "Foil Edition B" variant. Signed dates all show 5/2/2021 so it's likely these all were from the ComicSketchArt batch. Same seller also 6 copies of the other foil variant that he claims are Kyle Higgins's personal copies and are labeled as APs, yet his picture shows issue 48/100.
Two things things stand out here. So yeah. Does this mean ComicSketchArt oversold its claimed 50 and is sold the APs? Does this mean that vetcomix (and perhaps JoeNavy) is Kyle Higgins? Likely not, but it's very weird. Also, the Census lists 28 SS copies for "Variant Cover F", 24 of which are 9.8s. "Foil Edition B" has 17 graded SS copies, yet only one of which is 9.8. "Variant Cover F" also has a ton of non-SS graded copies, so it's definitely supposed to be the 1:50 variant, but it looks like CGC screwed up. Foil Edition B just popped up on the census, so it's 99% likely these are the Montez foils.
On a final note, I don't have a problem with AP copies, but CGC SS grading them leaves a bad taste in my mouth. Maybe that's just me though.
