Hi All

Hoping I can get some help with a value of a coin my very ill uncle gave to his 90 year old sister, my aunt.
He is currently in hospice care and asked me to make sure that my aunt doesnt get taken when she sell it

I've just been researching current market values and was hoping someone out there that I can trust could help me / her out.

The coin is a 1909 S VDB, MS 63 RB, 1C
Certified by ANA/ PNG

Thank You
