Is that why most, but not all, teflon insulated wire was silver plated?

My understanding is that the Teflon-insulated wire uses silverplating
for a couple of reasons, related to the high melting point of Teflon
(and thus the high temperatures to which the wire is exposed when the
Teflon is melt-extruded onto the conductors).

I checked looked at a spool of about #20 stranded wire. It does look very shiny
like silver.
I thought it was odd looking at it. its made up of a tightly twisted center
section and a loosly woven outer section around the inner section. The TFE is
almost a fluorescent blue. Neat stuff. 19/32 strands.

This got to be audio grade !

It is likely SPC and is Mil grade. There is no such thing as "audio
grade". You have been talking to too many consumer electronics
salespersons.
