No idea on numbers apart that both versions were total sell outs within a week. So if you find out how many were produced I think you'll have your number Strange card you got with yours as well. Maybe there were two prints of that as well? Does it say NOT FOR SALE on it? If not it will be a normal printed phone card that you can buy from NTT card stockists. Yakumo
It does indeed say 'Not for sale' in the bottom right hand corner. I prefer this care to the Sega Direct edition as it has more fan service.
