I recall reading about a monster in AD&D 2e that was a gold piece, but had a stinger that existed in another plane of existence. The extra-planar stinger made the monster very difficult to detect and to defend against.
Do any of you remember this monster and can you help me locate a name/stats for it?

I believe this is the Lock Lurker from several AD&D 2e publications. It was first featured in Forgotten Realms creator Ed Greenwood's regular column, "The Dragon's Bestiary," in Dragon magazine #139 (Nov 1988, pp. 70-71). Next, Greenwood put it in the Forgotten Realms adventure Haunted Halls of Eveningstar (1992), and then the Forgotten Realms Campaign Setting (1993). It was also in Monstrous Compendium Annual Volume I (1994) and lastly in the Priest's Spell Compendium Volume III (2000).1 (Special thanks to @SevenSidedDie for additional research!)
The fullest descriptions, along with pictures, are found in Haunted Halls of Eveningstar, Forgotten Realms Campaign Setting and Monstrous Compendium Annual Volume I.
Reproduction of stats for AD&D 2e is likely copyright infringement, so I won't be posting anything too specific, but ...
The stinger "is powerful enough to pierce any armor" and contains 40+ uses of venom that can stun, slow and potentially paralyze victims.
A google search should give you any other information you may want.
