Silver coin oberservations

Hadn't priced average circulated U.S. silver coins (those minted 1964 or earlier) on eBay in a while.

But as I scanned some of the coin rolls moving this week, they seem to be selling at a slightly higher premium than I recall in the past. Some online coin dealers also seem to be listing product at more of a premium than usual, despite the fact silver's been back under $30 an ounce for a while.

So which is it? Is the "paper" value of silver too low, or is consumer demand for the coins especially high?

Or maybe it's just a market fluke falling somewhere in between.

I'm also curious whether what happened in Cyprus might have anything to do with a possible rise in domestic demand.
