PC on some G3s

[respositob]

I've been collecting G3 ponies for a while now, and throughout the years, I've ended up with some duplicate ponies. I'm considering selling them on eBay (unfortunately, I will not be selling the ponies on the arena since I'm not yet old enough), but I don't know whether to start the bid at the standard 99 cents or higher. All of the ponies are out of package but near mint.  I'm considering selling:

Heather Winds
Banjo Blue (is missing the magnet on her hoof)
3D symbol Rarity (is missing one of the hearts the dangle from her 3D cutie mark)
Gem Blossom
Twinkle Twirl

If you guys have an idea about how much they are individually worth, please let me know. Thanks!
