Why does it say "Ein Kesef Nechshav"?
1.
Rashi (Melachim I, 10:21): None of the Kelim were of silver, for silver had no importance 1 .
2.
Yalkut Chadash (David, 64-65): Shlomo considered silver to be worthless, and discarded it. Hashem said, due to this he will need to take [Tzedakah] from people 2 .
2)
Here it says that silver had no importance in the days of Shlomo. Below (verse 27) and in Melachim I, 10:27 it says that it was like stones!
