1963 Scottish Shilling incorrectly formed
This Shilling does not appear to have been formed correctly could you advise please.
You are correct, Grant. This coin is an 'error coin' and collectors seek them. That means they are worth some money. My estimate for your coin is $10 to $20 US dollars.
Here are two links. The first is to a page that explains errors like yours. The second is to an eBay page with a coin like yours than sold for $15.
