That is my best guess also...It would be interesting if anyone has an =

Ha!..We I am a sceptic and have a heavy belief in science... so that =
conspiratorial theory
was not plausible...My only other notion was that someone saw me do it =
and
after I left for a service call, melted solder and took dime...but =
knowing the other
tech...probably not...
Thanks guys!


  Was that one of those really old dimes ... back when they were 95% =
sikver ?
  =20
  I suspect that it was still there, but had done a shape shifter trick.
