PC some G1 ponies

[Crystal Valley]

Hi, I made some search on the forum but I could find a PC for these ponies, I need to know if they're over priced or not please (I don't collect ponies for a long time so sorry if I ask for something pretty common)

Big brother Barnacle (good condition, just on or two little marks on it)
Spain Hopscotch (had little highlight mark on her :/ )
So soft Heart throb (good shape too but her flock look yellowed)
Italian Starshine with tropical hair (cutie mark rubbed and a little yellowed)

Thank you ♥
