For those who may be interested, here is my attempt at figuring out a simple version of the chords:

The Tinker's Coin by Jack Hardy

Intro:
Em D / C D / C Bm /
C Em / D C D

C                            D
Come all ye lads and lasses near
   C                   D
A story I will tell to you
   C                         Bm
About a cold damp night like this
      C             D C
When shelter I was seeking
    D                C    G
A traveler passing through


(chorus:)
    Em                         D
This coin's been haunted by the sidhe*
          C                           D
It shall bring you joy or bring you grief
    C                      Bm
Depending on the works you do
      C                   D       C
What once was mine now belongs to you
      D                C
To a traveler passing through

If Bm is too hard for you this works fine with Bm7. I also don't see any issue with dropping the G at the end of the verse.

I will also post a new thread on this topic.
