[NJARC] Coherer Filings

[Al Klase]

Folks,

The recent discussion of the TELIMCO Wireless Telegraph set, reminds me 
that I have had a coherer demonstration on the back burner for a long 
time.  I had a reasonably sensitive coherer worked up, but got stalled 
on the relay etc.

I want to get back to this but I've lost my stuff.  What I need most is 
an old Canadian five cent piece, one with high nickel content. You'll be 
able to pick it up with a magnet.  May apply to dimes and quarters as 
well.  Check your piggy bank, please.

Al
