Komentarz do Wyjścia 38:25

'וכסף פקודי בעדה מאת ככר וגו, the author explains how the amount is arrived at, 1 talent being 3000 shekel so that the 600.000 half shekel per head collected amounted to 100 talents, plus the small change mentioned here.

וכסף פקודי העדה מאת ככר, “and the silver contributed by the men of the congregation who had been mobilized for military duty,…amounted to100 talents.” Some commentators, basing themselves on the failure of the Torah to describe this silver as a “תרומה,” or a similar expression as used with the gold and copper contributions, that a great deal of silver was donated, and the reason why the total was not revealed here was that here we are only interested in how much of it was used in the actual construction of the Tabernacle. The balance was given to the Temple treasurer for use directly or indirectly in maintenance work, as and when necessary, as well as in the purchase of the animals of the mandatory communal offerings, especially at times when there was a dearth of voluntary offerings. If so, the scholar who holds that the tribe of Levi was also counted at the time of the first census is correct, as the shekel contributions of these Levites would make up the surfeit handed over to the trustee in charge of the Temple treasury.
