Commodore P500

Related - I have not seen any American B500's in a while. Got me thinking; I wonder if there are more B500's or P500's left today. I am pretty sure more B500's were produced, but you never see them, must have all vanished. It seems like a cache of P500's appeared in late 1990's, serial numbers in the 1200-1400 range or thereabouts.
 
I think I've only seen one B256 in a few years. Is that rarer than a ?500 ?
 
DO you mean high-pofile CBM 256-80 or the low profile B256 (prototype)?

There were maybe 3 (?) NTSC B256-80's and of the these I am unsure if they all have CBM ROMs from Commodore. Two were probably from the CBM lab. The B256's that I know of did not have a name plate, the name B256 is not official as far as I know.

The high-profile CBM B256-80's are maybe a little less rare as B-128's.

The B500 would be more common than the P500 but much less common than the B-128.

my educated opinion, rare to common:
B256 (B500-256) low profile (3-10 made)
B700 (high profile US)
P500 (only US were prototyes, ~1000 produced in Europe. Manuals for B series has P500 with full specs
B500 (original B series product launch, 1000-3000 produced)
CBM 256-80 (5000 produced)
B128-80 (10,000 produced)

note some high-profile systems may also have the 8088 co-processor installed, which makes them a lot rarer. i.e it's much harder to find a CBM 256-80 with an 8088 co-processor installed.
