Artifacts found from exploration

Since Voight has a main function of restoring and accepting artifacts, I think he should get a mention. You can sell to Voight in his shop, and he can take it with his artifact function. Two different ways.

However, both methods give the same results. Since this artifact cannot be appraised for a higher value, there is no difference in turning it in to Voight or selling it to any npc shop.

If the artifact could be appraised or each path had different results then there would be a point in mentioning Voight.

You don't get skill training if you don't turn it into Voight, though.

They're two separate methods. End of story.
