Lavinia bought 1,000 ounces of silver when the price was $33 an ounce. Recently the price was $22 an ounce. How much less is Lavinia’s silver worth than when she bought it?
The initial value of the silver that Lavinia bought is 1,000 * $33 = $<<1000*33=33000>>33,000.
The current value of the silver is 1,000 * $22 = $<<1000*22=22000>>22,000.
Thus, Lavinia's silver is now worth $33,000 - $22,000 = $<<33000-22000=11000>>11,000 less than when she bought it. Answer: \boxed{11,000}.
