I do not know how many were really shipped, and yes, they seem to be pretty uncommon, but it sounds like more than samples. Actually, some seem to be for sale on ebay ;-).

... The first NxPCI AT motherboards were shipped at the beginning of September 1995 after they were first announced in fall 1994. Motherboards featured support for EDO and Fast Page memory up to 768MB DRAM, up to four IDE devices, an on-board floppy controller, two serial ports and one parallel. It had four ISA slots and three PCI slots. Prices for a complete configuration, motherboard, CPU and heatsink were at $339 in combination with the Nx586 P90 and $439 with a P100.
... With a big player like Intel, getting a foothold in the processor business is hard. To gain the buyers attention continues price drops had to be made. By the time the Nx586 was actually for sale, the entry Nx586-P75 cost $404, the P80 $477, $539 for the P90 and the P100 was priced at $777. With new price cuts in mind Nexgen sought ways to reduce costs. One way was to make production of the Nx586 more efficient, fit more die's on a wafer. A die shrink was announced in the first half of 1995. ...
Nexgen discontinued its Nx586 P75 and P80 around August 1995. Demand had shifted to higher performance parts and NexGen needed the capacity for the imminent rollout of its new P120 and P133. Prices were once again reduced from $299 to $245 for the P90 and from $399 to $340 for the P100. In the mean time Nexgen was still trying to close additional deals for the manufacturing of motherboards and chipsets. To date motherboards were only manufactured by Alaris and chipsets by Fujitsu.
For over a year now Nexgen was shipping FPU less Nx586's, but this was about to end. In November 1995 Nexgen announced the Nx586 with integrated FPU, the Nx586 Pf100 and the faster Nx586 Pf120. The CPU and FPU would packaged together on a Multichip Module and manufactured by IBM. The Nx586 Pf100 would be available in December and the Pf120 was scheduled for Q1 1996.
