HP-27S 50th Anniversary Limited Edition really?

[Mick_Go]

I wonder how much this special calculator could be worth? Probably much more than I paid for it... When I bought this calculator, I didn't really question the origin of this 50th logo. All I wanted was an HP-27S and its manual in good condition for my HP Pioneer/voyager collection. I started my collection less than a year ago. For the moment, I limit myself to the Voyager and Pioneer series since these are the models that were contemporary when I was in university.

I understand that I was quite lucky on this one!
