Here is a 1937 Silver ( .500 ) UK Two Shillings in UNC.

I combine shipping.  The combined rate is based on weight and usually works out at about 50 cents for each additional coin.  If you are bidding on more than one item for the duration of my listings ( about one week ) ask for a total or wait for my final invoice which will have a combined shipping rate.  The ebay generated invoice does not.  If you want a tracking number be prepared to pay parcel post rates.  Buyers outside Canada acknowledge that the sale is at their own risk.
