How much was a donation to the Bais Hamikdash in US Dollars?

Half_Shekel w notes

In parshas Terumah (Shemos 24:2)  Each Jew was commanded to give one half shekel to the Bais Hamikdash (Holy Temple) each year. The Chazon Ish calculates that a shekel was 16 grams (.51 troy oz.) of silver [Yoreh De’ah 182:19)]. On Iyar 6, 5774 the price of silver was $19.61 USD per troy oz. How much is one half shekel worth in USD (to the nearest cent)?

.51 oz. x $19.61 = 10.0011 = $10.00

$10.00 / 2 = $5.00
