G1 PC Sticker Help - I'm clueless!

[STLGusty]

Ok, so this never happens to me.  (And I hate doing PCs..I tried to scour the archives but was unsuccessful.)

My friend's neighbor was having a yard sale this past Friday.  She neeeever goes to yard sales, but she wandered over and saw some pony stuff.  She called me and asked if she should buy it for me (and if they were legitimate).

She described a couple Ponyville's for me, the La Ti Da Ponyville playset, a few G3s...I had her pick them all up.

Then she said there were these stickers that looked older and were all in a plastic bag.  She was describing them to me and it sounds like they are G1 puffy stickers.  Not just any puffy stickers.... Seamist, Sand Dollar, etc.  It sounded like she read off all the adult sea ponies!  She also read off some other ones, but I kind of stopped listening when I heard the seaponies since I never really hear their names haha.

I asked her if any of them were still new - had their backing or sleeve, etc...  She said NO, but they still looked good.  I had her pick them up.  I'm supposed to swing by today to grab them so I'll know more later.

I was fortunate enough to own my set from when I was younger (now if only I could find those dang shells...who has the dang sticker but not the shells?!?! UGH), so I'll probably be putting these up for sale.  Thing is----I have NO clue how much to ask.  I thought they were a bit harder to find, but I have ZERO idea. 

To make a long story short, any PC help on the following would be great:
-puffy Sand Dollar
-puffy Whitecap
-puffy Wave Jumper
-puffy Seamist
-puffy High Tide
-puffy Sea Breeze
...(***And note - I'm NOT POSITIVE she said all of these seaponies, but I'll just ask now just in case I luck out and get them all lol)

I also remember her saying these...
-puffy Baby Blossom
-puffy Baby Surprise
-puffy Windy
-puffy Something New
-puffy Tiddlywinks

I asked her to ask if they had any actual PONIES...but apparently they had sold them at a garage sale a loooong time ago, and they had just recently found these in their basement.  Apparently they used to have a small collection, and now their daughter liked some of the newer ones (hence the Ponyvilles/G3s).  Small world!

Any help would be GREATLY appreciated!  Thanks!

Yr 3 adult sea pony stickers are very rare. On original backs they're at least $80. If they're used they're still worth something, not sure how much.

If they're on their backs, I'd  like to treat myself to one or two.
