PC on a few ponies - G1, 3, 4

[Zilla]

Hello! I have not been in the pony scene for about four or five years now so please forgive me if I'm posting in the wrong place! I poked around first and I think I'm doing this correctly but if not please let me know. I didn't see any recent PCs for some of these ponies unless I missed them.

I just took my collection out of storage and have a few doubles I'd like to get a price check on! I've been out of the loop for so long I've got no clue what they're worth.

G3 -

G4 -

2012 US Mcdonald's ponies (Applejack, Fluttershy, and Lilly Blossom) - mint in bags

G4 Blind Bags -

Wave 4 - glitter Twilight Sky
Wave 5 - Princess Cadance, Princess Luna
Wave 7 - Misty Fly, Lucky Clover, Cherry Fizzy

Thank you so much!!
