Template pricing: Unique vs regular

Hello there,

I've recently gotten back into designing templates and would like information on pricing that's got me a bit confused. When I go around to some of the larger template sites (templatemonster) I normally see a "Regular" price for a template, which usually seems to be less than $100, and then a unique price...which can be over a $1000. Now are the extremely high unique prices just a market ploy to keep people buying the cheaper version and hoping that pays off?

I ask because i've recently completed a template I would like to put up for sale, it's 3 pages (1 home, 2 sub) each coded in validated xhtml/css....now I think this is worth more than $100, but I can't honestly see someone forking out a figure like $1200 for it, so i'm just curious where these numbers come from.

Thanks for the help
