What's the market these days for NOS 70's/80's cartridges and/or tonearms?

When writing my post for this thread, I probably should have been clear to indicate the purpose of my question was with a view to sell the NOS items I originally obtained for a second vinyl system project, but have now changed my mind.  At the same time, I didn't want to appear to "sneak in" items for sale via the question, so I just asked the general question regarding the current market for items such as I've mentioned.  Sorry if I've wasted anyone's time by the lack of clarity.   Yet, the feedback and responses thus far have been helpful, nonetheless.

What you got then? 

Dear @nolojunko : Always exist some interest in NOS audio items ( vintage ) but you don't need to ask/thread for that you just need to put an advertize here in Agon site and you will have first hand experiences about.

Agon gives you the opportunity to put on sale even through an auction or other alternatives to your items been sold.

Here in Agon are several audiophiles that can be interested about including me, just disclose it through an Agon advetize.

Regards and enjoy the MUSIC NOT DISTORTIONS,

The difference between audiogon and better platforms like ebay and US Audio Mart is the listing fee. Nobody charge listing fee, except audiogon!

On Ebay you pay fee only if your listing is sold.

On US Audio Mart you don’t pay anything at all in any situation even if you sold your items. It’s free platform and extremely popular.

Another new platform is Reverb.

But Audiogon will charge their free just for listing, they want you to pay them even if you item remains unsold (and most likely it will be unsold for a long time). 
Auction is very bad idea for beginner if you don’t have followers and feedbacks, your item can be sold with very little interest for very low price if it will be an auction.

Thanks so much you guys.  I guess because I have no feedback (never been a buyer or seller here, since almost all my sales have been private party or dealer sales and/or trades), and I had thought Agon buyers are a bit picky about the lack of sales history.  But perhaps I should give some listings a try, as you suggest.

I don't have a lot of items, but do have a few I believe are desirable, e.g., Shure V15 Type 4, NOS; Stanton 681EEE MKII, NOS; SME3009R, NOS, unopened; 1957 TD124 (first year production, likely Sept S/N) from estate sale (it came with a Rek-O-Cut 120, and everything functioned fine).  Other items are just vintage HiFi equipment, of which I purchased new in mid-late 70's, that I previously had an nostalgic attachment to, but fortunately for which I kept all boxes and manual - - like Pioneer Spec 1 preamp, JBL4311WXA, Phase Linear 400, and, most recently I decided to sell my Herron VTPH-2A phono pre (only 40 hrs on it, so it should go quickly).  Again, I'm not trying to elicit buyers in any respect by identifying what particular items I'm interested in discovering the market for purposes of listing appropriately in accordance with, especially, Agon standards, etc.
