How Much Are These Saturn Games Worth?

[baad bwoy]

Hi can anyone help,
One of my friends is looking to raise some money, and is considering selling his Saturn games collection, which includes:

Radiant Silvergun excellent condition (minus spine card)
Thunderforce V (I think this still includes the spine card)
Powerdrift (again includes the spine card, I think)

Does anyone have any idea what these games are worth.

Thanks
