You are correct, only 20 of these Papersafe Satoshi Note's where made. Official sales thread:

I'm hereby announcing that I'll be the EU distributor for the new Papersafe - Satoshi Nickel Notes. I'll be the only person in the EU selling these and I only have 20 notes (out of only 100 notes). The PaperSafe - Satoshi Nickel Note is the third in the Papersafe Wallet series and the second of the Blockchain Mining series. It has a printed face value of 50.000 bits or 1/20th of a Bitcoin.
As I'm a Papersafe distributor, my notes will be slightly different. My forum name is printed on each note and the envelop will be stamped with my name. See the pictures below to see how this looks.
This thread also contains an Imgur album with more close-up pictures if anyone wants to see the special markings:

I'm very interested in seeing how much it fetches, also, Xprim777 how did yogg's note get at your place (just saw that I sold #237 to yogg)?
