Hi all,
I just spotted an auction on eBay for 40 IBM SMS cards.
It sold for over $2,000 (!)
Does anyone know if this reflects collector value or the
value of the gold content?
Also, what’s the current value of a set of SMS cold contacts?
OH, no WAY on the gold content. SMS was used in the early
days where gold went for $28/Oz. But, it couldn't have been
put on very thick for card fingers. Some other
manufacturers used gold as the etch resist, as it was
impervious to ferric chloride. But, still, those SMS cards
would only have a couple US$ of gold on the whole lot of 40!
