What are these worth, and what can I sell them for?


Hi,
Just joined, and this is my first topic Hello everyone.  I have a set of Yamaha NS-10 speakers in good to excellent condition, and would like to sell them.  I can't find anyone who has these for sale so I have no idea what price to put on these.  They work great! I use them all the time with my stereo system.  Love the sound!
I read the Wikipedia info and got the story of what they were used for.   
Here are some links to pictures of them that look just like mine

Ok Ok, I get it!  They are not worth very much, Bless you all! but I already new they were not worth much, just wanted to put an accurate price tag on them that made sense.  I didn't just buy them I have had them for years, and they're not going to goodwill, although a very kind thought.  So go ahead and say what you will,  I really like the retro look of these and it brings back memories of when I was a kid playing records on my old record player, Good Memories!  They are old and we have come a long way since, but don't forget what got us here.  Wikipedia is showing a picture of the later model and I do believe this was covering a range of speakers made throughout the years.  They started making these in 1978 and they changed over time.  That is what made this so confusing.  Anyway Thank You All for you input!  and now I will sell these now to a person that would love to enhance a retro room with some nice music coming through these retro speakers, that will enhance this type of interior design.  Thanks
@stereo5 - Thanks for that Kruipen link.  It is new to me a wonderful resource.
