My guess is somewhat around

Ist -

Ohm (if you are very lucky).

Necros have 75 and 125 as breakpoints and most use Spirit, so they need 2/20s.

2/15 can still have some use since some prefer other shields, like

Homunculus. But 2/15 are like 5x more common and have a smaller audience, hence much less value.

Yours also only has 2 to a skill tree. Curses is not a big deal but weaker golem and other summons further decreas the value compared to a GG one.

The res are nice but too low. Both poison and fire can have some use, especially when combined with psn sunder (for Poisonmancer) or fire sunder (

Corpse Explosion, but unusual).

There is a guy trying to sell a 2pnb/20 with 29 fr for 2

Ber for 2 months without luck: trade/stone-gorget-t1573389.html#p3894786

So be ready for a long sale and be ready to sell for less if you find a buyer.
