How much is a Kikar? Why does the Torah reckon 1775 Shekalim as a fraction of a Kikar?
Rashi (on Pasuk 24) and Rashbam: 1 Kikar actually equals 60 Manah, and a Manah = 25 Sela'im (Shekalim), 1 in which case 1 Kikar = 1500 Shekalim. Only since a Manah shel Kodesh is double that of a Manah shel Chol, 1 Kikar = 3000 Shekalim.
1 The Shekalim mentioned in the Torah are all Sela'im. Throughout Shas, 1 Sela = two Shekalim (See Targum Onkelos and Targum Yonasan on Pasuk 26).
