Current metal values (was What's 6 Feet Tall and Weighs 1, 500 Pounds?)

In the late 70's I lost an HP 2116 to silver and gold value. They wanted and got $3000 for it for metal scrap alone. The main values supposedly was in silver. I was told that 360's had more silver in them than gold, and it is now near or at an all time high value as well. I also was told that University of Missouri, Rolla's 360/50 went for around 25,000 in the early 80's for scrap. They were given 4341's by IBM to replace the /50, later upgraded by IBM at their cost. UMR had purchased the 360/50 in an unusual early buy in 1969 or 1970, when the usual procedure was to lease. University of Missouri, Columbia had a 370/158 at the time, don't know if it was owned, but most likely was as well. There was a service company, Sorbus which merged with another large service company, Braeden in the early 80's again who had a 360/40 for test purposes in Anaheim, CA. I'm not sure what happened to it. They were in bankruptcy, and I tried to obtain this machine, but never could find someone who would release it for sale. someone in the organization hopefully saved it, as that was the hangup, it was held for someone else to buy from the estate.
