what is the character requirement level, any sockets? Without more helpful prefixes/sufexes (resist all) this may not be very valuable. Amazon for example has a choice of griffion for end game or CoA for dueling. FRW is great for dueling, but it need other helpful mods to be valuable imo.
I found this:
Circlet +2 Amazon Skill/ +30% FRW / +17 STR / +40 LIFE / /29% EDef / 2 open Sockets
Sold for about 1600 fg which at the time was about 2 ber.
I’ve seen other similar selling for around the same 1-2 ber. But the big difference is 1v2 sockets. Even so I still think you can get at least 1ber+ To 2ber
To be better it would need 2sockets instead of 1, all res or another useful mod like + life and higher dex or strength
