The promise of outrageous returns is why some of the world's best stock pickers are, at times, penny stock investors. Peter Lynch has and still does enjoy the stock market's super-cheap seats. The Royce Low-Priced Stock fund crushes the market by betting on stocks trading near or below $10 a share, including Ivanhoe Mines (NYSE:IVN).

Even the All-Stars in our 115,000-strong Motley Fool CAPS community take to penny stocks. More than a few have been richly rewarded.

Pennies from heaven
So why not invest in penny stocks? I suppose because the SEC has warned us about them. But what if we take the agency's definition literally and limit our choices to stocks trading between $1.50 and $5 a share? And what if we further limit our choices to four- and five-star stocks whose market cap doesn't exceed $2 billion, but is at least $250 million? Surely our new CAPS screener would return some winners, right?

This week, 31 stocks made the cut -- not including our last topper, infoGROUP. Let's move on to mineral rights holding company International Royalty (AMEX:ROY), which has a small but strong following in our CAPS community:

The thesis here is simple: Buy up mineral rights and collect income from whatever is extracted from its lands. "Mining royalty company that essentially invest in various mines and therefore collect a small percentage either of the ore that comes out or of the resulting income," wrote CAPS investor heym0n in June.

Jim Cramer was bearish on International Royalty last summer, and he was right. But now, with shares of International Royalty down more than 55%, I sense a bargain. I know that sounds crazy; shares of International Royalty trade for roughly 60 times normalized earnings. And yet, in the most recent quarter, per-share net income tripled. Royalty revenue was up more than 50%. Outstanding numbers like those will always command a premium multiple.

But that's my take. I'm more interested to know what you think. Would you buy shares of International Royalty at today's prices? Let us know by signing up for CAPS today. It's 100% free to participate.

See you back here next week with another penny stock from heaven. Fool on!
