Steve: Thanks for your response. I've recently been told the number is something like 27 ... but I can't verify it. As for the "error collectors", I don't know too many who chase after edge insert combo's. Most error collectors I'm familiar with are more interested in double-sided errors and completely different edge insert colors... so I don't really know where to price the edge insert variations. Your estimate is probably a fair one in my opinion, since these are variations of exisiting chips, not unique in the sense of one only of a specific design.... which would command a monster price.

As for the BAO-20a, I've not seen one offered for sale either. Dick Brach keeps telling me the price is too low also. I'm certain that it would bring a fancy price if put on the market. I hate to push up prices of chips I own in my own catalog. Hopefully, a 20a will surface and the market will truly decide what it's worth.
