Let me know what you think. This is what I came up with for the Treasure Hunter based on the PHB rules.
Treasure Hunter
Skill Proficiencies: History, Stealth
Tool Proficiencies: Disguise Kit, Thieves’ Tools
Languages: One of your choice
Equipment: Either a Disguise Kit or a set of Thieves’ Tools, a small excavation kit that includes a shovel, gardener’s pick, bucket, and 50 ft. of hempen rope, a belt pouch containing 10 gp, and any one item on the trinket list that acts as the first treasure you discovered
Feature: Finder’s Keeper’s
As a Treasure Hunter, your livelihood and reputation depends on the quality of items found while scouring the land for lost artifacts and valuables. You’ve developed a keen eye for the approximate worth of objects. You gain advantage on Intelligence (Appraisal) rolls.
Suggested Characteristics
Treasure Hunters are found among all cultures, races, and religions. They range from archeologists, historians, and teachers all the way to criminal organizations and petty thugs. There isn’t any one thing that defines you, but there is one thing that binds you: the accumulation of loot.
