Decided to try and profit off some items I’ll never use but never sold anything before so I’m not sure on pricing, definitely need gold for undercity runs and enchanting costs but a half decent rolled amulet would help too. Any help would be great I have a 4GA BLUE ROSE and a 4GA PENITENT GREAVES

If you think you have enough materials and need gold then sure sellem all…
For gold i suggest playin highest difficulty that you can easily clear nightmare dungeons (like 5min max per run)… So you get the highest gold multiplier…
Also use a NM dungeon that grants the 30x gold drop…
Also… if youre doing seasonal content then you can go get the extra gold boon potion drop from that…
Now fly through the NM dungeons and sell everythin you dont want and youll rack up gold rather quickly…
Other suggestion is run helltide and open lots of chests… While targeting whispers and turn in as many whispers as possible… also equip the gold potion from seasonal if you have that…
Quick n efficiencient as possible is key… try not to get distracted with other things… unless its a priority
Hope that helps ya out some
Pricing is easy. Just look up the same items on trade site and see what they have gone for with sold filter and what is available now. Blue Rose and Pentitent are not meta items but you can make sell to a person if they have max aspect or close to it. I happen to buy items to use on eternal that are near max so I offer 5B each of these if they are max or a couple % from max.
Old thread I know just wanted to say I miss the bonus opals and chorus of war incense definitely took those bonuses for granted
