Slayers cel question

I'd purchased this cel from a dealer's Magic Knight Rayearth pile: http://felicitychan.rubberslug.com/gallery/inv_info.asp?ItemID=44636

But it turns out that he's actually Eruk from Slayers. I've only seen a few Slayers episodes and have never (knowingly) purchased cels from the series. I was just curious about how rare and desirable the character is and what price range he might fall in.

Thanks:)

P.S. I'm asking out of curiosity, not because I'm planning on selling him.

Hi,

he's Sylpheel's father and only appears in an episode or 3. The thing is, he's not an important character. I'm afraid he's not worth much o.o
