That's probably due to the fact that Freescale (who I believe purchased the chip fab from Motorola) only manufacture the chip in sets of 10,000 and the 68030 and below are marked as "discontinued", per unit price depending upon model is ~$100. I guess resellers/trade sellers have to get their markup somehow.
I think that Motorola just split its chip fabrication devision off from the company can called it freescale ?
