This is either worth about twice the price of the original (Which wouldn't be a lot) or you could probably get quite a bit for it. No name isn't uncommon, but from a Structure/Evo/Starter? That's pretty
beast.
As said, I'd hold onto it. Put it on the front page of your folder and try and get a load more like it. People'll be like "WOAH!?! This guy is serious business." and they're more likely to trade with you.
Seems fickle, but it works like a charm for me. People saw that I had every version of
Dark Paladin, I put the JP
Dark Magician on there (Not even slightly difficult to get) and a couple other
rare Spellcaster/Magician cards and people paid attention to the folder more.
