Het piers have black "train track" markers along the sides of the belly. The second pic you posted shows what I'm talking about pretty clearly so yes he has them but that's not proof of a het as not all hets have the markers. The markers just up your odds a little. Do a search on here for het pied markers on here there have been several threads about it.

As far as price it's not too far off I paid 50 for my male het pied and I have seen several on kingsnake in that range.
