They could be a completely different chip, relabelled. If your time is precious, or your money, I'd recommend you reject them and get a refund.
But of course if you are curious, you might wonder what they really are.
I already asked for a refund. If they don't ask for them back, I may investigate further. You could always (attempt to) de-cap it and see what's what. They may micro controllers as Martin A pointed out
I will try to get some 6502s from reputable suppliers, albeit more expensive. Or I could have another go at ebay's lottery...

RDY and BE are other pins you should tie high with resistors. But they shouldn't affect Phi1/Phi2 outputs.
Yes, did that too. Sorry I missed that.
Also both supposedly GND pins (1 and 21) are not connected internally, don't know if this would be expected, although I would suppose they should be.

I've not yet tested any of these, though I can certainly wire up a NOP pullup/down and see what my oscilloscope says it's doing, if anybody's particularly concerned. (Or maybe even whack them into my Apple I replica if there's real doubt about whether or not they're CMOS parts.)
I would test them just in case. But it seems people are having different luck, so who knows.
By the way, the eBay seller I bought from was adeleparts2010.
