Warren Buffett Answers Question on Silver Trade

The question was asked, "Did you sell your silver position to the banks that started the Silver backed ETF?"

Buffett's answer, "I don't know who bought it from me, but they are smarter than I was about it."  He goes on to say, "I bought it too early. I sold it too early. Other than that it was a perfect trade."

I'd always wondered what happened to that silver trade from a few years back . . .
