Fake or Real China 1948 50 Yuan?

So, i've crossed with this one at an auction, not sure if forgery or authentic (new to banknotes).
If authentic, which grading would you give?

Red flags: Way too many Chinese banknotes, way too cheap.
Maybe sellers ignorance, maybe not.

I bought a 60 note set from China during this era, including the note shown for $17.

Of course these are fake, which I knew when I bought them. 

Definitely fake. I bought the 60 note set mentioned by Roland, knowing that they were fake. I paid about $6 or 10 cents per note. I bought a customizable stamp set and marked every one “forgery by Chinese criminals” so that my son, when he inherits the collection, know that they are bogus. They are in my China (PRC) album. On eBay some USA sellers are auctioning these as real or at least not declaring them to be forgeries. A clue to know if it is a scam is that the selling price does not in any way reflect the very high catalog value of a real note. The sellers market them at a low price to get rid of them.

I have about 90 forgeries in my collection, mostly Chinese made. I decided to add them, all properly marked my me as “forgeries” to the collection as a personal interest.
