About Sunken Blocks Of Gold

While traveling the seas using the fast travel ships - Skippers. The captain gave me 3 sunken blocks of gold, saying that he acquired it after uncovering a sunken treasure chest.

Is there anything significant about them? It says they are "Misc. Items" But I feel like there's more to them, is itlike Cassiop's Masterpiece? Where it can be sold to a specific merchant for 3 le?

 

Not for 3LE .-.
Selchar. There's a merchant.
Have fun with your 3EB

 

Oh okay, thanks man!

 

Not far from selchar are the seevale reefs where you can aquire alot more stuff. Good for early-game emerald grinding if you have a Breathing Helmet.
