What is the value of a Fiji Edward VIII?

The only Fijian coin to have any reference to King Edward VIII was the 1936 Fiji Penny.

A Fiji 1936 cupro-nickel Penny (Edward VIII), uncirculated and in absolute mint condition could fetch up to $5 USD. If it has been circulated but still in good condition, it might fetch anything from $0.50 to $3 USD.

There were 120,000 minted.
