Fake or old bicycle 808?2

[hahaharvey6]

Hello, I recently purchase 10 decks of bicycle 808. I am not sure if they are fake or like very old stock because in the A of spades of one deck it says
W1601. According to Lee usher's post, the lettervW was printed on 1916, 1936 and 1956. Im not sure if it is original or fake.
