Gold nuggets are also salvaged from shipwrecks including the
Espadarte shipwreck in 1558.
This ship was Portuguese ship that sailed to India in 1554
and broke her mast on the return voyage around the Cape of Good Hope and have
Arqueonautas certificates.
These nuggets were well preserved a s they were wrapped and
in strong storage boxes, as if not they would have been worn down smooth by sea
currents
The Portuguese were strong traders in Africa and controlled mining
operations in Mozambique where alluvial was found in rivers instead of mines
,so was easy to find and transport but most gold was alluvial so was lot work
to find and process but there was plenty inexpensive labour in Africa to
process this alluvial gold in late 1580s to take back to Portugal for smelting
to gold bars
So you can own virgin specimen gold from this famous shipwreck that has certificate of authenticity
