The Royal Mint included a commemorative £5 coin marking Princess Diana in its 1999 annual Proof set. It is a commemorative issue, so its collector value is separate from the £5 face value.
How to identify it
Check the 1999 date, the Princess Diana design and the finish. An individual coin, an annual Proof set and a coin with original packaging are different items for valuation purposes.
Value guidance
Condition, finish, packaging and demand affect the price. Compare completed sales of the same version and presentation. Avoid treating an asking price or a description such as “rare” as proof of value.
