Beautiful historical George V Silver SHILLING, dated 1921 (Best Date.)  The coin is identified as KM# 816.a, Spink 4023.

This is a very interesting coin. According to Krause & Spink, this is the best date. The authoritative Spink catalogue of British coins lists variants - at least two types of pre-1926 Obverses for Shillings. This coin corresponds to the 'nose to S' identifier. The website Numista lists additional Reverse variants - you decide which one is this coin. 

Your coin will be shipped as soon as payment is received. If you have any questions let me know before you bid.  Shipping in the US is 5. This does not apply to foreign purchasers, ask me before you bid!     

I combine shipments. Thanks and good luck!
