Is this minifigure with a white shirt showing a little orange monster worth anything? I have a LEGO minifigure that I am unable to find anywhere on the internet. He has the classic smiling yellow head, with a white torso portraying an orange monster shaped as a 3D cube/hexagon, with little vampire fangs in its mouth and crossed eyes. He has simple red legs. Does anyone know how much it might be worth? I am thinking of selling it.
The whole minifig assembly reminds me of of those services that allow you to print your own image on a torso piece such as Minifigs.me.

I wouldn't be surprised if this minifig was made using the same service as I cannot identify the graphic. I suspect this minifig could have been ordered as a promotional item.
The actual parts themselves are so common that they might even be the cheapest parts you could get to make a minifig. The parts can be sourced easily for under a dollar assuming you bought the torso without a custom print.
