PC on max gold sundering half moon of enchanting (10/8, 19%, req 10)

As the title says, I've got a Max Gold Sundering half-moon of Enchanting,
Sunder 10/8, enchant 19%, +15% dmg in stance.

I'm not sure what to expect from it, because I put it up for sale, thought it'd get at most 20K, but then this happened:

and the last bid was over 200K - can anyone give me a PC on this so I know whether those two guys were just playing the fool on my thread? I don't honestly think it's worth 200K, IMHO, and I'm the seller :P.
