People have the weirdest ideas about coins, ofcourse you can't discount them if you're interested in gearing the entire raid.
Also people are fucking stupid when it comes to bonus rolling. Take Purified Bindings, if you weren't rolling that shit when several people still needed it just because you think you are next in line/might win a roll you are a douchebag. Heavily contested items are the best to roll for to gear up the raid.
About your specific case it's hard to say as an outsider.
