realia price

Salve sodales

I´ve been sniffing around to look for an stipulated price for a realia, obviously, i found nothing.

I know that MSMV but anyway i whould like that you share how much could a covenant ask for the realia inheritated from the mage Someonus Ex Idontknow and that for sure they are not going to use.

how whould you process the price? per pieces? per lvls? paws or pounds?

differences betwen habillities and arts?

Thank you in advance for your apreciations.
