coronets price check

do these have any value?

IMHO

Um or

Mal for the fire sorc one. Cold res rolled low, frw is not needed for most sorcs, extra gold is not as useful as other affixes (life, strength, ...) and it's "only" +2 fire not +2 all sorc skills.

For the assa

Coronet I would say

Ko or

Fal or some

Perfect Gems. Life and all res are nice but frw is only 20%, energy is a low roll (20 possible) and not as useful as strength or dexterity and enhanced defense adds no value.
