Item Quantity Support (legacy) gem

I only play for a month or two every year or two, and am thinking of cashing in one of my old IIQ support gems to bankroll my and some friends' characters.

I know poe.ninja lists an uncorrupted 20/20 as 86 div, but:
1) it's a low volume item (so price is uncertain)
2) it also says there are ~400 listed (so might be too high)
3) market manipulation is a thing, esp. for low-volume, high-value items (so it might be too low)

just wondering what people think an *actual* reasonable selling price would be

If you're not using it id sell at face value. Maybe add a few divine and drop it down.

I have some legacy items but dont play standard, if i did id rather just take a couple of divine hit as Its easy enough to make back and enable a build.
