This file (nickel2head.txt, written 20 Aug 2003 by James Waldby) 
explains a way of making a "two-headed coin".

Jim Sehr emailed me 11 pictures illustrating the process.
I combined some of them together into three pictures:

nickel21.jpg (64KB) - Nickel chucked in shop-modified soft
collet, being bored; nickel in collet after boring; closeup 
of two bored nickels.

nickel22.jpg (48KB) - Round stock with .800" faced and turned;
bored nickel in place on end of stock; using tailstock, live
center, and bushing to hold nickel in place for turning to
remove rim.

nickel23.jpg  (28KB) - Closeup of one bored nickel with rim,
and other bored nickel with rim removed; closeup of nickel
as pressed together.

Here is Jim's description of making a two-headed nickel --
   I used a soft 5c collet and bored it to hold the nickel.
   Then I made two nickels bored out to .800 dia x .036
   deep. [ Half of coin.]
   Then I faced and turned a piece of stock to .800 then
   I put the bored out coin over the turned dia. Then I
   used a live center pushing a bushing against coin to
   drive it. Took light cuts about .01 and turned it to
   .800 bore size. then I pressed coin slug into the bored piece
   and ended up with two headed nickel with no seam showing.
   Worked great.

   The reason to use a bushing to hold coin [instead of live 
   center by itself] was the point of the center would mark 
   coin [otherwise].  I used .625" dia out of my scrap bin.

Here's my comments, slightly rephrasing the process --
   Nickels are about .073" thick and .835" wide.  He cut
   away a .8x.036 section of the Monticello side of each nickel.
   He then cut away the rim on one of them, making a .8x.036 
   disk, which he pressed into the .8x.036 hole of the other.

   To cut away the rim, he chucked a .8" cylinder and pressed
   one of the bored nickels onto it, holding it there by tailstock 
   pressure while taking light cuts on the rim.
