True penny stocks are a minefield, but small-cap copper beauties can be one way to easily double your money.

There are also those companies whose shares trade at the other end of the price spectrum. I call 'em "three-digit stocks," though if they're anything like Berkshire Hathaway , they can trade in the four-, five-, and six-digit range, too.

While a penny stock might not be a good buy simply because it's cheap, a three-digit stock shouldn't scare you away just because it carries a hefty price tag. Handsome is as handsome does, so we check in with the Motley Fool CAPScommunity to see which ones might have the best chance of further succeeding.

Below are a handful of these high-priced highfliers, and we'll take a look to see if some members of the investor-intelligence database think they can maintain their lofty prices.
