Now that I've done the bonus sticker numbers, let's move on to the next two things - the foil stickers and the Wacky subsets.
The foil stickers are easy. Only ANS3, ANS4, ANS5, ANS6 and ANS7 had them and all of them had 10 stickers each. The only differences were these:
*ANS3 had all-new Wackys that weren't found anywhere else and all of the other four sets had classic Wackys from the OS run.
*The first four sets came in classic foil and rainbow foil versions, while ANS7 was classic foil only.
Of course, everything in Chrome was foil, but it was foil cards instead of foil stickers and each one of the 110 base cards had nine variations: basic, refractor, blue refractor, gold refractor, atomic refractor, X-fractor, superfractor, blue Ludlow and gold Ludlow.
Now for the subsets. They are as follows:
*ANS6: 2 - What's In The Box?!? (10) and Make Your Own Wacky Packs (10)
*Flashback: 1 - Lost Wackys (8, all from the OS run and all of which were absorbed into the base stickers)
*Flashback 2: 1 - Lost Wackys (9, all from the lost 1992 Series and all of which were also absorbed into the base stickers)
*ANS7: 3 - Wack-O-Mercials (20), Wacky Websites (3) and Wacky Cereals (6, all of them from the OS run)
*ANS8: 2 - Pack To The Future (10) and Wacky Packages Go to the Movies (subset version) (8 (it was supposed to be 10, but two of them - Ironed Man and Avatart - were pulled and remain unpublished as stickers [UPDATE: Avatart has finally been released as a sticker in Wacky Packages Go to the Movies (series version) in the Classic Films subset (see below), while Ironed Man remains unpublished as a sticker to this day]))
*ANS9: 3 - Awful Apps (orange backs) (10), Lame Games (10) and Wacky Cereals (9, all of them from the ANS run)
*ANS10: 5 - Awful Apps (purple backs) (10), As Screamed on TV (10), Lost Wackys (3, all of them from the lost 1992 Series), Wacky Cereals (9; again, all of them from the ANS run) and Wacky Billboards (6, all of them made as both card backs and box-topper inserts)
*ANS11: 4 - Coming Distractions (9), Rude Food (9), Lost Wackys (3; again, all of them from the lost 1992 Series), Wacky Cereals (9; once again, all of them from the ANS run) and Wacky Billboards (6; again, all of them made as both card backs and box-topper inserts)
*Chrome: 4 - Wacky Ads (36 (IMO, this one should've been put in with the base cards)), Lost Wackys (10 (with 8 from Flashback, one from OLDS3 and one from the first and fourth printings (of a total of five in all) of the Abrams Books art book Wacky Packages), Cutting Room Floor (20, all based on rough art from the 1970s and first released as characters only in the Topps Wacky Packages "17th Series" 3-ring binder) and Where Are They Now? (5, all OS Wackys redrawn with modern-day (as of 2014) packaging artwork)
*2014 S1: 4 - Ridiculous Reads (10), Terrible TV (10), Lost Wackys (3, the first one from the 1985 series and the other two from the ANS run (the second one was originally intended for ANS2 and the third one was originally intended for ANS3)) and Wacky Billboards (6; once again, all of them made as both card backs and box-topper inserts)
*2015 S1: 4 (the first three of which were, once again, absorbed into the base stickers) -"Crazy Collectibles" (5),"Batty Baseball" (10), "Coming Soon" (5) and Wacky Billboards (6, but this time all six of them were done as just card backs, while only four of the six were done as box-topper inserts (the other two were never released as such for unknown reasons))
*MLB: 5 - Active Stars Autographs (5), Mascot Autographs (5), Seat Relics (5), Ticket Relics (10) and Box Toppers (4). It'll sure be interesting to see what comes next, if anything!
UPDATE 2: 50th Anniversary - 14 (in fact, this entire series was the first of two that were nothing but subsets) 50th Anniversary (9), Crazy Apps (9), Crazy Celebrities (9), Crazy Cereal (9), Crazy Pop Culture (9), Crazy Movies (9), Crazy Music (9), Crazy Politics (9), Crazy TV (9), Crazy Video Games (9), Best of the '80s (10), Best of the '90s (10), Best of the '00s (10) and Old School (10 (I like to call this subset Wacky Packages Old School 5.0)).
UPDATE 3: Here are the OLDS subsets:
*OLDS 3: 1 - Wacky 1967 (11, including a checklist (nine of the 10 were released before in Flashback (all of which, as the subset's name suggests, were from the Die-Cuts) and one was both brand-new and originally intended for the Die-Cuts as a 45th sticker, but was never released as such)
