It could be worth between $20 - $25 if in AU (almost uncirculated) conditition. The good news is that I'm sure you wouldn't have any problem selling it (if high grade)...since there are insert replacements with the FDV prefix & collectors often like to form "sets" (* a replacement, radar, low number,etc) of certain prefixes. You'd probably be wise to hang onto it... (and perhaps work on a set yourself?)
- Hope this helps...
