I am finding that selling items to players must be higher than NPC value. To stop yourself from getting ripped off.
At the moment '-encrusted' weapons are very high, this is great if you don't wish to sell to players, however it's terrible for selling to players as they don't want to spend a lot on a weapon that's got no buff and is only a collector and is pretty easy to get through loot. Many other weapons are like this, so I came here to complain that they should be dropped in NPC value.
I would say it's fine and I would just shrug it off. However it's all about RP, selling to players creates interactions with players, creating RP.
