Tom,
your questioning is a strawman-alike questioníng. Now I happen to know which
Indian tribe that mined the silver,
for that an for the silver in Icelandic artifacts. That doesn't alter the
simple fact that Ivar Bardson on travelling the voyage for collecting the
Tiundetaka(yes that was then name for the tithes 'taken'(=collected) from
the dioceses under Gardar Greenland. Ivar Bardson's voyage took several
years, as did the other known collector's voyages when Greenland and Vinland
was on the agenda. Latest documented collection was from 1500's(!) btw.

Fact is that the silvered coconut bowl came from the tithes collected in
Vinland North America. Not Greenland. Not Iceland nor anywhere else in the
Old World.

You better try to live with that instead of trying to find 'what if'
scenarios. Such doesn't alter the case at all.
