PC on some minis

Hey!

I just checked my miniature collection and I would like to have a price check on it. All of them are unded.

Gold:
King Adelbern
Prince Rurik
Celestial ox
Celestial rat
Dagnar Stoneplate

Purple:
Jora
Nian
Burning Titan
Koss
Flowstone Elemental
Palawa Joko

White:
Temple Guardian
Thorn Wolf
Jade Armor
Juggernaut
Roaring Ether
Raptor
Abyssal
Shard wolf

Also I have couple of Birthday presents from almost all years, what is the price for those? Is it worth the gamble to open them or should I rather sell the present? Lastly, I have couple of BD Vouchers in my backpack, what are they selling for?

Thanks in advance!

BUMP!
I know that the white ones are probably worth ~500g, but what about the golds and purples? And the price of bd gifts would also be much appreciated.

Thanks!
