Oldschool Crystalline Sword with bugged mod.

Hey...
i bought this OS crysta today...
It has a bugged mod... Has 20/20 sundering on it but doesnt show in the name ->Bug....
Might put it on auction soon, or maybe just keep it.
Any clue on the estimated value?
Im pretty sure its a unique (because of the glitch), also, crysta on OS dont drop anymore... so even without the glitch it might be worth a good bit?
Anyone have a clue why it might be glitched? are there other glitched sword like this?

Picture is broken so we can't see (or at least I can't.)

I had this sword for quite some time untill 3 years ago.... Cant remember for what i sold it then but i recon it is arround 100-150e now, there's no market for these anymore unless someone makes a bid war with me if you put it on high end.....

it is a real bug, i use to have that sword, sold it to someone for 750e 2 years ago.

More opinions pls?

Most likely 150-200e+ (Depending if there is a bidwar with any collectors out there, if so maybe 250e+. )
