Monetary Value Leopard Geckos

I'm trying to figure out how much my hatchlings (how long are they considered hatchlings??) are probably worth. I'm guessing not too much, but I'm hoping for some more knowledgeable opinions!
I got both my adults as class pets a couple years ago, but brought them home after I moved schools. I don't know anything about their genetics or history. I was totally shocked by the black and white babies, but have discovered that this means they are Mack Snow. I'm guessing this comes from my female, since she's the lighter of the two adults. They older two are about 2.5 months old, and one has gotten more gray, but hasn't shown much color change besides that.
I hope to give or sell them to friends, so I'm not really planning to use this information for profit, just to satisfy my curiosity.
