Oddly enough it seems the same is true for Mansa's trip. Except that as regent, he gave himself the funding, twice.

However, as wikipedia notes: ( https://en.m.wikipedia.org/wiki/Atlantic_voyage_of_the_predecessor_of_Mansa_Musa )

1. No african artifacts have ever been discovered in South or Central America.
2. Only one of the ships returned, and it only reported the existence of the "Canary Current" which that ship did not enter.

In addition. The dark skin of some South Americans is genetically distant to modern Africans, but has ties to the same markers in some asian cultures, implying its addition was prehistoric and happened in the old world.
