Foreign coins: unwanted / charity

I was in LloydsTSB t'other day and saw a green collecting box with a
Barnados sticker asking for unwanted foreign coins. As it happened, I
had a few kicking around (having come back from USA recently), and they
have now found a new home.

(No connection with LTSB or Barnados, but happy to have found a useful
home for those pesky foreign coins that usually float around the bottom
of my desk).
