I imagine this ship would be a treasure trove.
A lot of the treasures will come from the crew cabins and cargo hold. Coins, jewelry, pocket watches etc were valuable. If the cargo was unique it could be valuable. Much like with the Titanic, some shipwrecks are famous across the region and some are only famous locally. One famous ship the Pewabic was carrying copper ingots and those can go for over $1500. Other things like china, and utensils may only have historic value and zero monetary value.
