Questions

How much is a 1918 sixpence worth?

A genuine 1918 sixpence in barely worn condition (Extremely Fine) has typically sold for $420 at Australian auctions, with the middle half of sales between $360 and $1,050. Better-preserved examples sell for more.

How do I know if my 1918 sixpence is genuine?

Work through the checks above. They cover what genuine examples show and what altered or different versions don't. A photo can't prove a coin or note is genuine, so for a valuable find, ask a professional numismatist or a grading service before you sell.

Should I clean it?

No. Cleaning leaves fine scratches that collectors spot at once, and cleaned coins and notes sell for much less. Keep it as it is, in a paper envelope or a coin holder.
