White Spot/ Red Discosoma Shroom Retail Price?

[Dark_Knightt]

So i just got my first corals for my birthday a few days ago
-Green Tip Purple Torch
-Green Bubble
-Purple Candy Cane
- GSP
- Duncan
- White Spotted Red Discosoma Shroom.

My friend at the LFS told me that it was a pretty rare coral, so i started researching but i couldn't find anything on it or its price.
If someone could please tell me the retail price cuz i got it for free as a gift. Thanks a lot #reefsquad
