Ive got here a puzzler for me any way?
The coin is a Hong Kong one cent 1923.
Same size & colouring as an old British Penny.
but
On the front:
GEORGE V KING AND EMPEROR OF INDIA
and profile of GEORGE V
however on the rear:
HONG-KONG ONE CENT 1923
Any ideas on this one , valuation if any?
Is this an error or this is how they were made?
Thanks again.
