How much would you pay for classic Game Boy titles on 3DS Virtual Console?

If NES games were around $5 on Wii’s Virtual Console, I’m going to take a guess that original black & white Game Boy titles will clock in at $3. To be honest, you probably would have a lot more sales if you just went with $1 each, though I doubt Nintendo would ever go that low.
