Hello,
I saw somenone said in trade/sale forum that Motorola CPUs with XC at beginning of CPU description are Samples ... Engineer Samples. That is true ?

That could be strange because most of my Motos are XC not MC.

XC simply means they have not been fully qualified (have not been completely tested.)

I think this is true for early Motorola families - 6800 and other 680x (but not more recent 68hcxx parts), 68000, 68008 and 68010.

"XC" on 68030 and more modern families means that the parts are not fully qualified. 68030+ engineering samples have prefix 'PC'.

I didn't mention 68020 because I still don't know if XC68020 are engineering samples or not.
