Oh this is amusing, a "Victorian" sgian for $450.

These were mass-produced in the 1960s and 1970s, plastic handles, EPNS mounts (nickel plated over base metal).
I have a 1978 catalogue in front of me that has them for $13.50. I know all about them, I bought one then from that very catalogue, it was my first sgian.
