NOS Shure V15 type III cartridge opinions


I know this sounds crazy but going thru boxes stored in closet for the past 40 years and found one of these I had purchased in 78 as a spare and never used. My question is should I open it up and give it a spin on my vintage TT or keep it to replace my in use cartridge until it goes south or open it install to see what happens? Wished I had another headshell. I read this was the best mm cartridge build, great all around sound and unsurpassed tracking. 
Or put on market? I'm leaning toward trying it out but then again?

'Thanks, I thought about putting on the market but based on what I read in reviews or opinions I would hate to walk away and not know what everyone raved about back then. Can't remember if I ever heard one or not. It's a quandary for sure. Maybe someone who has used it can chime in. I'm sure there are better ones out there now but it sure would be nice just to see. I suppose I could try it and then sell as slightly used.
Thanks Dave that helps a lot. I noticed you mentioned a yellow pull out elliptical stylus. The label on the box says it's elliptical but the stylus is a pull out black  and the body is silver. Do you know if stylus colors changed somewhere along the way?
I'm becoming more familiar with it thru reading and am more than likely going to try it. I do blues and rock so this may be right up my alley. If it pleases I'll hold onto it

Thank for the input. Consensus seems to be that the suspension for the stylus may be suspect after all this time. I did visually inspect the cartrige and stylus with a magnifying glass and see nothing visually other than that it is pristine.  Just in case I did look for a replacement stylus and found only aftermarket stylie ranging from 13 to 88 dollars. A Phanstiel, supposedly made in switzerland, is 25 dollars and the highest priced ones are from Japan and shipped from there. Does anyone have any experience with these aftermarket stylus?
Any information would be helpful and appreciated

To all that have responded,  you rock my world.  Thank you so much for your input/suggestions. 
I will try the NOS as is and if need be get the best rated albeit most costly stylus if needed. I think I'll start by obtaining another headshell first for ease of swapping out between cartridges. It's also most economical. 
Thanks again

FWIW, while surfing found a NOS the seller is saying is new in box for 499.00. Looks exactly like mine. Y'all go get it.
Thank you dlcockrum for the link to jico. If need be I can order the vr35e or vr35 he directly from them at 79 or 119 dollars respectively. If I do need to order I will go with the HE hyper eliptical stylus.
