For now, a cliche concept, average art and a character that make absolutely no sense. If the appraiser job is so bad, and there is no apparent way to get strong, what inspired him to go for adventuring? And what made the adventurers pick him for the team? This needs some development, but the current trend in low-level fantasy stories is to start a story with no background.
Seriously, identifying may not be great as an adventuring skill, but it has great utility value, so it should be quite useful in several other jobs. As a merchant, guild worker, etc. It's only a trash skill in combat, although it could be useful at the start to learn about your enemies. So, in the end, it's only trash because the author says so.
Also, to some commenters above, this is not isekai.
