Coin UK Crown 5 Pounds NIP 2000 Queen Elizabeth Mother Centenary 100th Birthday

Description

Great Britain/UK Crown (5 pounds/) celebrating the 100th birthday of Queen Elizabeth the Queen Mother in 2000.
The beloved Queen Mum passed away in March, 2002.
Coin has never been circulated, staying in its presentation packaging for the last 20 years.  Made of cupro-nickel, it features profiles of both Elizabeths: the standard Queen's profile with "Elizabeth II.D.G. Reg. F.D. 2000"; and the back has the Queen Mother with little flag-waving fans, and the words "Queen Elizabeth the Queen Mother, 1900-2000, Five Pounds," and her signature. Even though uncirculated and sealed in package, there appears to be a tiny mark at 7 o'clock (pictured).  Not sure if it's a flaw in minting, but it doesn't seem to be present in pictures I've seen elsewhere.
Slipcase has the Queen Mum as she appeared at 100 years and her timeline on the back cover.  Inside is a booklet with photos of her at various points in her life.  The coin is plastic-sealed and is sandwiched between the two outer pages.  Slipcase and booklet opened, but in mint condition.
Please ask questions before bidding.  Hopefully, it's sufficiently described.
I ship same or next business day.
