It was won by a member who knows what he's doing.
Puma Gold are very desirable razors, so in great condition they go for quite a bit.
On this particular razor the top two bidders were willing to spend 500 for it, the one under them only slightly above 100.
Note that a razor is worth different amounts to different people. And as with any scarce things it's the balance between supply and demand that determines the 'worth'.
