I posted the same question on another coin forum ..and it was suggested this was actually a die flaw ..and not uncommon.. rgds VS

Hi all .. As you will realise I have just joined the group .. I have a reasonable collection of coins ..some found with a metal detector in my youth ..some purchased along the way. Included in these are some nice Charles Halfcrowns .. These include 3 Tower mint.. 1 Chester Mint 1 Bristol Mint 1 Oxford mint and 1 York mint. If these are indeed genuine the last 4 I suspect are rare-ish. Certainly they cost me enough when I bought them some 30 years ago.. The York Half Crown has always intrigued me as to it's authenticity .. Not so much the others. The York coin has some silver splashes on the reverse ..and this always had me wondering ..as the only way this could have happened assuming it's genuine ..is after the hammering of the coin.. Has anyone ever seen anything like this before ? I'm attaching photos of the coin ..and would appreciate any expert comments.. rgds VS
