devils contract is an older, true 10 drop, asian shard so harder to find. but historically the graphic doesnt go for much. personally id value it at 150m, but if you find someone who really wants it it could be higher. maybe double that.
the candles sell well for 200 to 250m. again, you may be able to squeeze 300 if you find someone who really wants it and cant find it for cheaper. the candles were a 20 base drop, but with the random points system and double bosses on that shard theres about 35 of them.
