Welcome to my guide all about the new undated 20pence piece.
I thought i would explain what to look out for when purchasing one of these of ebay. The coin has to be undated on both sides. That means no date on the Heads and no date on the tails.
DONT get caught out and buy 2008 undated coat of arms 20p with a date on the HEADS side.
Hope this has been helpful!
